The Black Cat Bar or Black Cat Café was a bar in San Francisco, California. It opened in 1906 and closed in 1921. The Black Cat re-opened in 1933 and operated for another 30 years. During its second run of operation, it was a hangout for Beats and bohemians but over time began attracting more and more of a gay clientele. Because it catered to gays, the bar became a flashpoint for the nascent homophile movement. The Black Cat was at the center of a legal fight that was one of the earliest court cases to establish legal protections for gay people in the United States. Despite this victory, continued pressure from law enforcement agencies eventually forced the bar's closure in 1964.
