Treasure Island is an artificial island in the San Francisco Bay between San Francisco and Oakland. It is connected by a small isthmus to Yerba Buena Island, a naturally-formed island. It was created in 1939 for the "Golden Gate International Exposition" by dredging up dirt from the bay. The Administration Building, a Streamline Moderne-styled remnant of that World's Fair, is now the Treasure Island Museum.

During World War II it became part of the Treasure Island Naval Base. In 1996 it and the Presidio Army Base were decommissioned, and opened to public control, under stipulations.

Treasure Island is now part of District 6 of the City and County of San Francisco.

A substantial part of the island is undergoing environmental cleanup by the federal government.

The island has no gas station, and is served by a single bus, the San Francisco Municipal Railway 108. It has a job training center and is home to many low-income San Franciscans.

The island has a raised walkway which circumnavigates almost its entire bulk, which is popular for recreation. Sea lions can be observed in the water from the shoreline, and construction of the new eastern span of the San Francisco-Oakland Bay Bridge can be observed from the eastern part of the island.

Treasure Island's old aircraft hangars also served for three years as the site of Comedy Central's Battlebots television show.
