SeaWorld San Diego is an animal theme park, oceanarium, outside aquarium, and marine mammal park, located in San Diego, California. SeaWorld San Diego is an accredited member of the Association of Zoos and Aquariums.

SeaWorld was founded on March 21, 1964 by four graduates of the University of California, Los Angeles. Although their original idea of an underwater restaurant was not feasible at the time, the idea was expanded into a 22-acre (8.9 ha) marine zoological park along the shore of Mission Bay in San Diego. After an investment of about $1.5 million, the park opened with 45 employees, several dolphins, sea lions, and two seawater aquariums, and hosted more than 400,000 visitors in its first year of operation.

SeaWorld currently leases the land from the City of San Diego with the lease expiring in 2048. The premises must be used as a marine mammal park, and no other marine park may be operated by SeaWorld within 560 miles of the City limits.
