Alcatraz Island is an island located in the San Francisco Bay, 1.5 miles (2.4 km) offshore from San Francisco, California, United States. Often referred to as "The Rock", the small island was developed with facilities for a lighthouse, a military fortification, a military prison, and a Federal Bureau of Prisons federal prison until 1963. Beginning in November 1969, the island was occupied for more than 19 months by a group of American Indians from San Francisco, who were part of a wave of Indian activism across the nation, with public protests through the 1970s. Later, in 1972, Alcatraz became a national recreation area and received designation as a National Historic Landmark in 1986.

Today, the island's facilities are operated by the National Park Service as part of the Golden Gate National Recreation Area; it is open to tours. Visitors can reach the island by ferry ride from Pier 33, near Fisherman's Wharf in San Francisco. In 2008 the nation's first hybrid propulsion ferry started serving the island. Alcatraz has been featured in many movies, TV shows, cartoons, books, comics, and games.
