阿尔卡特拉斯岛（英语：Alcatraz Island，英语俗称The Rock），俗称恶魔岛，是位于美国加州旧金山湾内，距离旧金山市区1.5英里（2.4千米）的一座小岛，面积0.0763平方公里，四面峭壁深水，联外交通不易。早期岛上建有灯塔，是一军事要塞（1868），后来被选择为监狱建地，在1933年至1963年间被设为恶魔岛联邦监狱，关押过不少知名的重刑犯人。1970年代，全国掀起一股国家本土主义浪潮，在此期间，阿尔卡特拉斯岛曾被一群来自圣弗朗西斯科的本土主义者占据19个月之久。1972年，阿尔卡特拉斯岛成为一个娱乐景点，并于1986年被授予美国国家名胜。

Alcatraz Island is located in the San Francisco Bay, 1.25 miles (2.01 km) offshore from San Francisco, California, United States. The small island was developed with facilities for a lighthouse, a military fortification, a military prison (1868), and a federal prison from 1933 until 1963. Beginning in November 1969, the island was occupied for more than 19 months by a group of aboriginal people from San Francisco who were part of a wave of Native activism across the nation with public protests through the 1970s. In 1972, Alcatraz became a national recreation area and received designation as a National Historic Landmark in 1986.
