OC Fair & Event Center is a 130-acre entertainment, education, and community hub in Costa Mesa, best known as the home of the annual OC Fair. The Fairgrounds are active throughout the year, hosting over 150 events annually, like concerts, festivals, markets, educational programs, community events, and family-friendly activities.

The Fairgrounds are home to Centennial Farm, a three-acre working farm where visitors can learn about Orange County’s agricultural founding through gardens, animals, and hands-on programming. Heroes Hall Museum & Education Center honors Orange County veterans and other U.S. service members through rotating exhibitions. Visitors can experience the personal stories of veterans, told through artifacts and historic media. Both provide free, family-friendly education.

Each summer, the OC Fair takes over Costa Mesa with larger-than-life fun. Think big flavors and big energy across acres of rides, games, exhibits, and entertainment. You’ll find live performances at Pacific Amphitheatre,
art and agriculture competitions, unexpected photo ops, and enough food to fuel a full day of
exploring.
