Richard Holt Locke (June 11, 1941 – September 25, 1996) was an American actor in gay erotic films of the 1970s and 1980s, who went on to become an AIDS educator and activist. As a performer in adult cinema, Locke has been credited with being one of the "earliest and most widely emulated VCR stars" in gay erotic cinema, as well as someone whose performance and physicality contributed to the evolution of gay sexual behavior in the 1970s and 1980s.
