Stanley Tookie Williams III was an American gangster who co-founded and led the Crips gang in Los Angeles. He and Raymond Washington formed an alliance in 1971 that established the Crips as Los Angeles' first major African-American street gang. During the 1970s, Williams was the de facto leader of the Crips and the prominent crime boss in South Los Angeles.

The Crips are an alliance of street gangs that is based in the coastal regions of Southern California. Founded in Los Angeles, California, in 1969, mainly by Raymond Washington and Stanley Williams, the Crips began as an alliance between two autonomous gangs, and developed into a loosely connected network of individual "sets", often engaged in open warfare with one another. Its members have traditionally worn blue clothing since around 1973.
