Colston Richard Westbrook (1937–1989) was an American teacher and linguist who worked in the fields of minority education and literacy. At the University of California, Berkeley, he established a program of prison outreach and approved students from the Bay Area to serve as volunteers. Some of the participants from Berkeley and two former prisoners at Vacaville Prison were among the founding members in 1973 of the radical leftist group known as the Symbionese Liberation Army.
