Oceanside USA 250 Festival

America's turning 250, and O'side is throwing the kind of party that'd make the Founding Fathers loosen their collars. Join us at the Junior Seau Pier Amphitheatre for an afternoon of live music, local flavor, and classic Americana. Country star Craig Campbell headlines the stage alongside a full lineup of performances, while hundreds of local vendors, artists, and community groups bring the celebration to life. Enjoy chili cook-offs, kids grand prix, a full Fun Zone packed with free kids' activities, and plenty of good eats along the way. Come celebrate 250 years of community, creativity, and freedom the O'side way.
