Orange County California Fair Schedule

Orange County, California, is one of the most densely populated and economically diverse counties in the United States, and its annual fair reflects that urban and suburban character rather than the predominantly rural setting associated with many smaller county fairs. The Orange County Fair, commonly known as the OC Fair, is held in Costa Mesa at the OC Fair & Event Center and has become one of the county’s largest recurring public gatherings. Costa Mesa sits in central Orange County, surrounded by communities such as Santa Ana, Huntington Beach, Newport Beach, Irvine, and Fountain Valley, giving the fair a broad regional audience.

The OC Fair’s agricultural identity is especially interesting because modern Orange County is far more urbanized than the agricultural county that existed when the fair began. Citrus, vegetables, strawberries, dairy operations, livestock, and other forms of agriculture once occupied large areas of the county. Today, remnants of that agricultural heritage are preserved through livestock exhibitions, horticultural competitions, Centennial Farm, youth agricultural programs, and demonstrations that connect present-day Orange County residents with the farming history of the region.

For the 2026 fair season, the OC Fair ran from July 17 through August 16 under the theme “Your Adventure Awaits.” It operated for 23 fair days, Wednesday through Sunday, with the grounds closed on Mondays and Tuesdays. The 2027 fair will continue the annual summer tradition, but exact 2027 dates and programming should not be assumed until officially released.

Fair Overview and Fast Facts

The Orange County Fair is held at the OC Fair & Event Center, 88 Fair Drive, Costa Mesa, California 92626. The 130-acre event complex contains approximately 157,000 square feet of event space and includes permanent facilities such as Centennial Farm and Heroes Hall, making the property much more than a temporary fairground.

The 2026 fair operated Wednesday, Thursday, and Sunday from 11 a.m. to 11 p.m., while Friday and Saturday hours extended from 11 a.m. to midnight. Fair buildings closed earlier than the overall grounds, with buildings closing at 10 p.m. on Wednesday, Thursday, and Sunday and at 11 p.m. on Friday and Saturday.

The 2026 general admission structure was $13 for adults ages 13 through 59 on weekdays and $18 on weekends during the fair. Children ages 6 through 12 were $9, while children age 5 and younger were admitted free. Seniors 65 and older were $10 during the fair, with lower advance pricing available before opening day. An Every Day Passport was also offered for $60 while supplies lasted.

General parking in 2026 was $15 for cars and motorcycles, while bus and limousine parking was $30. Because Orange County Fair attendance is large and Costa Mesa is surrounded by heavily traveled urban roads, parking and traffic should be treated as a significant part of the visit rather than an afterthought.

The fair has also used controlled daily capacity in recent years. For 2026, the paid attendance capacity was set at 55,000 people per day. This makes advance planning particularly relevant during popular Friday and Saturday evenings.

History and Origins

The Orange County Fair has roots almost as old as Orange County itself. The Orange County Community Fair Corporation was formed in 1889 shortly after Orange County was established, and the first Orange County Fair was held in Santa Ana in 1890. Early fairs were much smaller than today’s event and concentrated heavily on livestock exhibitions, horse races, agricultural products, and other demonstrations of the county’s developing agricultural economy.

In 1894, the Orange County Fair Association took over organization of the event. By 1907, the fair had become an annual three-day event and adopted the “Carnival of Products” identity, reflecting the agricultural and productive character of early twentieth-century Orange County.

The fair moved among several Orange County communities during its early history. It was held in Santa Ana, later moved to Anaheim, and spent periods in Huntington Beach and other temporary locations. The Orange County Farm Bureau took over its organization in 1916, and an Orange County Fair Board was elected in 1925. That period also saw the addition of a rodeo and carnival in Anaheim.

The modern fairgrounds story began after World War II. California established the 32nd District Agricultural Association to operate the fair, and land formerly associated with the Santa Ana Army Air Base was selected for a permanent fairground. The first fair was held at the present Costa Mesa site in 1949.

The fairgrounds were already established before Costa Mesa became an incorporated city. When Costa Mesa incorporated in 1953, the fairgrounds became part of the new city. The site has remained the home of the OC Fair ever since, creating an unusual connection between a historic agricultural institution and one of Southern California’s highly developed urban regions.

Readers comparing California’s county fair traditions can move from the Nevada County California Fair Schedule to the Orange County California Fair Schedule to see how two very different parts of the state celebrate their local heritage. Nevada County’s fair reflects the Gold Country and western Sierra Nevada foothill character of Grass Valley, Nevada City, small-scale agriculture, livestock, and rural community traditions, while the Orange County California Fair Schedule highlights the much larger OC Fair in Costa Mesa, where agricultural heritage is combined with major entertainment, carnival attractions, competitive exhibits, Centennial Farm, and youth livestock programs. Together, the two schedules show how California’s county fairs can preserve local agricultural traditions while adapting to very different community settings.

Agricultural Competitions and Livestock Shows

Agriculture remains a visible part of the OC Fair even though most of Orange County’s former farmland has disappeared beneath residential, commercial, transportation, and institutional development. The fair preserves that agricultural connection through livestock, horticulture, specialty crops, youth competitions, and educational demonstrations.

Centennial Farm is particularly important. The three-acre working farm within the OC Fair & Event Center contains crop beds and livestock areas and is designed to teach visitors, particularly children, how food and agricultural products are produced. During the fair, visitors can encounter cattle, goats, sheep, pigs, chickens, rabbits, and other farm animals.

The agricultural exhibits also connect the fair to actual Orange County agricultural producers. Displays and educational materials have highlighted local agricultural names such as Tanaka Farms, Neff Ranch, and 5 Bar Beef, while large “Bounty of the County” murals on the fairgrounds commemorate Orange County’s agricultural roots.

Livestock competition is a major component of the youth agricultural program. The OC Fair Junior Livestock Auction includes market beef, goats, lambs, hogs, turkeys, broilers, and rabbits. Animals must meet the applicable show and market requirements before becoming eligible for sale.

The fair’s 2026 Junior Livestock Auction was scheduled for Saturday, July 25. Only qualifying market animals, including blue-ribbon market-ready animals and required champion animals, were eligible for the auction. The program provides a direct connection between Orange County businesses and agricultural youth.

Horticulture and specialty-crop competitions provide another agricultural avenue. Fruit, vegetable, floral, and California specialty-crop exhibits allow growers to present products even when their operations are much smaller than the large farms historically associated with Orange County.

Fair Schedule Structure

The OC Fair has a distinctive five-day-per-week schedule rather than operating continuously every day. In 2026, the fair opened Wednesday through Sunday and closed Monday and Tuesday throughout the season.

Wednesday, Thursday, and Sunday operated from 11 a.m. until 11 p.m., while Friday and Saturday remained open until midnight. This schedule creates particularly long evening periods on the weekend, when visitors from Costa Mesa and neighboring Orange County communities can attend after work and other daytime commitments.

The agricultural schedule operates alongside the public entertainment schedule. Livestock judging, competitive exhibits, agricultural demonstrations, youth programs, and educational activities have their own times, while carnival rides, food vendors, shopping buildings, concerts, and stage attractions operate according to their own schedules.

The Junior Livestock Auction is one of the more significant agricultural dates within the fair calendar. In 2026 it took place on a Saturday, while market shows and livestock viewing continued to form part of the fair’s agricultural program.

Entertainment varies by individual fair season. The OC Fair has a history of concerts, stage performances, motorsport events, family programming, community entertainment, competitions, demonstrations, and special themed activities. Visitors planning a particular day should check the annual schedule rather than assuming that every event appears every year.

Entertainment, Rides, and Midway

The OC Fair’s midway is substantially larger and more varied than the carnival area typically associated with a small rural county fair. Its Costa Mesa location attracts families and young adults from throughout Orange County, producing a busy combination of carnival rides, games, food stands, shopping, and evening entertainment.

The carnival includes rides designed for young children and families as well as larger attractions aimed at older children and adults. Height and safety restrictions differ by ride, so families should evaluate each attraction individually.

Food is one of the most recognizable features of the modern OC Fair. The fair’s large commercial food operation combines traditional carnival foods with elaborate specialty creations designed specifically to attract fairgoers. The Orange County setting also means the food culture reflects the county’s highly diverse population, with vendors offering a broader range of flavors than the traditional agricultural fair menu alone would suggest.

Live entertainment is distributed across the fairgrounds. The OC Fair’s entertainment program can include concerts, local community performers, specialty acts, family programming, demonstrations, competitions, and shows in dedicated venues such as the Pacific Amphitheatre and The Hangar.

Open Class and Amateur Competitions

The OC Fair’s competitive program extends well beyond livestock. Orange County residents can participate in a wide range of competitions involving art, photography, horticulture, culinary work, crafts, textiles, home-related skills, and other creative categories.

These competitions provide an important connection between the fair’s historic agricultural purpose and the interests of a modern metropolitan population. A resident of Irvine, Costa Mesa, Santa Ana, Huntington Beach, or another Orange County community can participate without owning a farm or livestock operation.

Entry requirements differ by department. Participants must follow the applicable competition rules, registration deadlines, delivery instructions, size requirements, and judging standards for the category in which they enter.

Judges evaluate exhibits according to the characteristics appropriate to each competition. A horticultural exhibit may be evaluated for quality, condition, maturity, and presentation, while photography and fine art are assessed under different standards. Culinary, textile, woodworking, and craft competitions likewise have department-specific requirements.

Ribbons and awards provide recognition to exhibitors, while selected departments can offer premiums or other prizes. For many participants, the significance of winning is less about the monetary value of an award and more about having their work publicly recognized at one of Orange County’s most visible annual community events.

Demolition Derby, Tractor Pulls, and Motorsport Events

The OC Fair has a stronger motorsport tradition than many county fairs because its entertainment program is designed for a very large Southern California audience. Demolition derby events have been associated with the fair’s entertainment program, and the Action Sports Arena provides a permanent venue for motorsports and other large-scale events.

Demolition derby participation is governed by vehicle rules, safety inspections, registration requirements, driver requirements, and competition-specific regulations. Vehicles must comply with the applicable rules before entering the arena, and safety procedures are an important part of the event.

Tractor pulls are less central to the modern OC Fair identity than they are at many rural agricultural fairs. Orange County’s urban development and the fair’s metropolitan audience have produced a programming mix in which demolition derbies, concerts, action sports, carnival rides, and large-scale stage entertainment can coexist with livestock and agricultural exhibits.

The fair’s motorsport events therefore represent one part of its broader entertainment identity rather than the central agricultural purpose of the event.

4-H and FFA Youth Programs

Youth agriculture is one of the strongest links between the modern OC Fair and its historic identity. The fair’s Junior Livestock Auction specifically supports 4-H and FFA agricultural education programs throughout Orange County.

The young exhibitors participating in livestock programs spend months learning how to care for animals, manage feeding programs, prepare animals for competition, keep appropriate records, and communicate their knowledge to judges and buyers. The public sees only the final show-ring presentation, but the project represents an extended educational commitment.

The Junior Livestock Auction creates a particularly strong community connection. Local businesses and individual buyers can purchase qualifying animals, while additional supporters can make add-on contributions to specific exhibitors. The 2026 program allowed online add-on contributions after the in-person auction.

Eligible 2026 auction animals included market beef, goats, lambs, hogs, turkeys, broilers, and rabbits that met the required quality and market-readiness standards. Grand Champions and Reserve Grand Champions in each applicable species were required to sell.

Centennial Farm adds another dimension to youth agricultural education. Created in 1989, the three-acre working farm was specifically designed to help children understand agriculture and its relationship to everyday life. Its gardens, livestock, educational programs, and Millennium Barn make agricultural education a permanent feature of the Orange County fairgrounds rather than something limited to fair week.

Fairgrounds Facilities and Layout

The OC Fair & Event Center occupies approximately 130 acres at 88 Fair Drive in Costa Mesa. Its permanent buildings and outdoor spaces make it capable of hosting a much larger and more diverse event than a temporary county fairground.

The property includes approximately 157,000 square feet of event space. Major facilities include exhibition buildings, livestock areas, the Pacific Amphitheatre, the Action Sports Arena, The Hangar, Centennial Farm, and Heroes Hall Museum and Education Center.

Centennial Farm occupies three acres and includes crop areas, livestock pens, and the Millennium Barn. The barn contains a milking parlor, demonstration areas, animal-related facilities, and educational spaces.

The fairgrounds also include substantial outdoor areas for the midway, food vendors, pedestrian circulation, community activities, and agricultural displays. Because of the size of the property, visitors should expect considerable walking during a full day at the fair.

Accessibility services and routes are incorporated into the event center’s operations, but visitors who require particular accommodations should review the current fair information before arrival. The scale of the grounds makes advance planning especially useful for visitors with mobility limitations.

Getting There: Directions and Logistics

The OC Fair & Event Center is located at 88 Fair Drive, Costa Mesa, California 92626, near the center of Orange County. Its location provides relatively direct access from Costa Mesa, Santa Ana, Huntington Beach, Irvine, Newport Beach, Fountain Valley, and other surrounding communities.

The fairgrounds are connected to the regional road system through Fair Drive and nearby major Orange County routes. Visitors approaching from Interstate 405 can use the Costa Mesa-area exits and follow local signs toward the fairgrounds.

Traffic becomes significantly heavier during fair evenings, particularly on Fridays and Saturdays. The combination of fair visitors, commercial traffic, carnival operations, and ordinary Orange County commuter traffic can create delays around the Costa Mesa area.

Parking on the fairgrounds was $15 for cars and motorcycles during the 2026 fair. Bus and limousine parking was $30, while passenger drop-off did not carry the bus-and-limo parking charge. Visitors should follow the current traffic-control instructions because parking arrangements can be adjusted during particularly busy events.

Volunteer and Vendor Opportunities

The commercial scale of the OC Fair creates opportunities for food vendors, merchandise businesses, community organizations, artisans, nonprofit groups, agricultural exhibitors, and other participants.

Commercial and concession vendors must meet the fair’s application and operating requirements. Food and beverage concessionaires have additional responsibilities because their operations must comply with applicable Orange County health requirements. The 2026 fair required food and beverage operators to participate in a mandatory pre-fair meeting involving supporting agencies, including the Orange County Health Department.

Vendor participation requires substantially more preparation than simply renting a temporary booth. Vendors may need to provide business information, comply with space and equipment rules, obtain appropriate permits or insurance, submit required staff information, and meet fair operating standards.

The fair’s commercial handbook establishes operational requirements for vendors, including booth access, staff check-in, deliveries, point-of-sale systems, parking, and settlement procedures. Businesses interested in participating should begin the application process well before the fair season because vendor selection and administrative requirements occur months before opening day.

Community entertainment provides another participation route. Local performers, organizations, and community groups can apply to participate in the fair’s entertainment programming. For the 2027 fair, community entertainment applications were scheduled to open January 11, 2027.

Economic and Community Impact

The OC Fair has an unusually large economic and community footprint because Orange County is a major metropolitan economy. The fair attracts visitors from Costa Mesa and surrounding cities, and their spending reaches beyond admission and carnival purchases to restaurants, fuel stations, retail businesses, hotels, transportation services, and other local businesses.

Its size also creates a substantial marketplace for commercial vendors. Food operators, merchandise sellers, artisans, entertainment providers, agricultural exhibitors, and community organizations all participate in an event capable of drawing a very large regional audience.

The fair’s community value is not limited to commerce. It preserves elements of Orange County’s agricultural past at a time when much of the county’s historic farmland has been converted to other uses. Centennial Farm, livestock competitions, horticulture exhibits, and the Junior Livestock Auction allow modern residents to encounter agricultural practices that were once commonplace across the county.

The event also reflects Orange County’s cultural diversity. The fair combines historic agricultural traditions with contemporary food, music, arts, entertainment, and community programming, making it a particularly useful illustration of how Orange County’s identity has changed since the first fair in Santa Ana in 1890.

Comparing Orange County Fair to Nearby Fairs

The OC Fair occupies a very different position from smaller agricultural fairs elsewhere in California. Nearby regional events include the Los Angeles County Fair in Pomona, the San Diego County Fair in Del Mar, and fairs in Riverside, San Bernardino, and other Southern California counties.

The OC Fair is distinguished by its Costa Mesa location, metropolitan audience, permanent 130-acre event center, extensive commercial programming, large carnival midway, major entertainment venues, and year-round agricultural education facilities.

Unlike a predominantly rural county fair where the surrounding farming economy remains the primary focus, the OC Fair preserves agriculture within a highly urbanized county. Centennial Farm and the Junior Livestock Auction are especially important because they provide direct connections between Orange County residents and agricultural education.

For Southern California fairgoers, the OC Fair is therefore both an agricultural heritage event and a major entertainment destination. Its scale, Costa Mesa setting, long history, and combination of livestock, food, rides, concerts, competitions, and educational attractions give it a character distinct from smaller county fairs.

Visitors should not assume that outside food, beverages, coolers, or other containers are automatically permitted. The fair maintains admission and prohibited-item rules that can change from year to year. Visitors should check the applicable year’s rules before bringing outside food or drinks onto the grounds.

The fair itself has a very large food operation, including traditional fair foods and specialty offerings.

How do I enter an item in competition at the Orange County Fair?

Residents enter competitions through the appropriate OC Fair competition department. Categories extend beyond agriculture and include areas such as art, photography, horticulture, culinary work, crafts, and other creative fields.

Each department establishes its own entry requirements, deadlines, delivery instructions, eligibility rules, and judging standards. Participants should review the applicable competition rules before preparing and submitting an entry.

Is the Orange County Fair appropriate for young children?

Yes. The OC Fair has extensive family-oriented programming, children’s rides, animal exhibits, agricultural education, games, food, and entertainment.

Who organizes the Orange County Fair?

The OC Fair & Event Center is owned, operated, and governed by the 32nd District Agricultural Association, a state of California institution. The district is responsible for the fairgrounds and the annual OC Fair, with numerous agricultural organizations, youth programs, vendors, performers, exhibitors, and community participants contributing to the event.

Is there camping available at the Orange County Fair fairgrounds?

The OC Fair & Event Center is a major event facility, but ordinary fair visitors should not assume that public RV or campground-style accommodation is available simply because the property hosts the fair.

Vendor, exhibitor, livestock, and event-related access can have separate arrangements. Anyone requiring overnight accommodation should make arrangements outside the fairgrounds unless the applicable year’s visitor or exhibitor information specifically provides otherwise.

What happens if the fair is cancelled due to weather?

The OC Fair operates in Costa Mesa during the summer, when ordinary weather conditions are generally compatible with its outdoor schedule. However, unusual circumstances such as severe weather, extreme conditions, public-safety concerns, or other emergencies can require individual events to be delayed, modified, or cancelled.

Orange County’s history also demonstrates that extraordinary circumstances can affect the fair. The 2020 OC Fair was cancelled because of the COVID-19 pandemic, marking the first cancellation since World War II. If an exceptional situation affects a future fair, visitors should follow the current fair administration’s instructions regarding schedule changes, tickets, exhibits, and special events.
