Pacific Ocean Park was a 28-acre (11-hectare) nautical-themed amusement park built on a pier at Pier Avenue in the Ocean Park section of Santa Monica, California in 1958. Intended to compete with Disneyland, it replaced Ocean Park Pier (1926–1956). After it closed and fell into disrepair, the park and pier anchored the Dogtown area of Santa Monica.
