Richard Harrison (born May 26, 1936) is an American actor and occasionally a writer, director and producer.

Harrison was very prolific and worked with most of the better-known names in European B-movies during the 1960s and 1970s, branching out to exploitation films shot all over the world in the early 1970s. He worked with directors ranging from established names like Antonio Margheriti and Marino Girolami to infamous Z-movie directors like Paolo Solvay, Godfrey Ho and Alfonso Brescia. Harrison's co-stars ranged from major and minor stars of the time like Anita Ekberg, Klaus Kinski, Fernando Sancho and Helmut Berger to obscure cult actors such as Mike Monty, Romano Kristoff and Mike Cohen.
