Music, carnival rides, dancing, food from around the world, and one of the nation’s oldest Cinco de Mayo parades are all part of this beloved Stockton tradition. Stockton is getting ready to turn up the music, fire up the carnival, and welcome one of the biggest community celebrations of the year. The 2026 El Concilio California Cinco de Mayo Multicultural Festival is returning to the San Joaquin County Fairgrounds for three full days of culture, entertainment, family fun, and community pride on Friday, May 1, Saturday, May 2, and Sunday, May 3.
