Coast Guard Island is an artificial island in the Oakland Estuary between Oakland and Alameda, California. It is home to several major United States Coast Guard commands and cutters, including the Coast Guard Pacific Area. From 1942 until 1982, the island was the site of the Coast Guard's recruiting training center (boot camp), enlisting and training hundreds of thousands of Coasties including many of the 214,239 who served in the Pacific and European Theaters of World War II.
The 67-acre (27 ha) island is situated in the historic Brooklyn Basin, now known as Embarcadero Cove. It is within Alameda city limits, but is tied to land only via a bridge from Dennison Street in Oakland.
The Island houses a number of U.S. Coast Guard commands and its facilities are managed by Base Alameda. Tenant commands include:

The facilities on Coast Guard Island also include an industrial service center, enlisted barracks, a medical and dental clinic, and public works facilities to service the island.
