On Saturday, June 27, 2026, the Oceanside Chamber of Commerce, in partnership with County Supervisor Jim Desmond, will host the Oceanside USA 250 Festival—a community festival honoring America’s 250th birthday at the Junior Seau Pier Amphitheater. Held immediately following Oceanside’s Annual Independence Parade, the festival is expected to draw thousands of residents and visitors downtown for an afternoon of live music, local food and beverage vendors, family activities, and community exhibits that showcase Oceanside’s pride and patriotic spirit.

As one of Southern California’s most diverse and patriotic coastal communities, Oceanside is the perfect place to mark this historic milestone. The USA 250 Festival will bring together families, local businesses, civic leaders, military personnel, and visitors for a unifying day of recognition, entertainment, and community connection.
