Oceanside Pier, Pier in Oceanside, California, United States

Oceanside Pier is a wooden pier 596 metres long, the longest wooden pier on the US West Coast, running from Pier View Way out over the Pacific. The current structure, the sixth on the site, opened in September 1987 and cost $5 million. At its foot stand the Junior Seau Pier Amphitheatre and the 17,000-square-foot Junior Seau Beach Community Center.

The first Oceanside Pier was built in 1888 at today's Wisconsin Avenue and was destroyed by storms in the winter of 1890. Melchoir Pieper rebuilt it in 1893 at Pier View Way, where all later piers have stood. Four iterations were destroyed by storms before the current pier opened in September 1987 at a cost of $5 million.

The pier is reached on foot from Pier View Way, where metered parking is available; pre-pay parking is along Mission Ave, N. Pacific St, N. Myers and N. Cleveland St. Parking rules are strictly enforced near the pier and harbor. The walkway runs the full length of the deck, and the far end is where the 2024 fire damage is being repaired.

The former Ruby's Diner at the pier's end, a 1950s-style restaurant opened in 1996 and vacated in 2021, was the point of origin of a fire on April 25, 2024, that destroyed the structure while about 90% of the pier stayed undamaged. Rebuilding is expected to start in mid-2027 at an estimated $17 million.
