The Junior Seau Pier Amphitheatre is an outdoor entertainment venue at the foot of the Oceanside Pier, on the beach just south of the pier entrance. The amphitheatre hosts summer concerts, outdoor movies, and community events, and its position on the sand with the Pacific as backdrop makes it one of the more atmospheric outdoor venues in the San Diego area.
The venue is named after Oceanside's most famous athlete. On summer evenings the site comes alive with the kind of relaxed beach-town event culture that distinguishes Oceanside from its more resort-oriented neighbours to the south.
