Clarence LeRoy Van Cleef Jr. (January 9, 1925 – December 16, 1989) was an American actor. He appeared in over 170 film and television roles in a career spanning nearly 40 years, but is best known as a star of spaghetti Westerns, particularly the Sergio Leone-directed Dollars Trilogy films, For a Few Dollars More (1965) and The Good, the Bad and the Ugly (1966). In 1983, he received a Golden Boot Award for his contribution to the Western film and television genre.

Van Cleef served in the United States Navy during World War II aboard a minesweeper, earning a Bronze Star for his actions. After acting on stage in regional theatre, he made his film debut in the Oscar-winning Western High Noon (1952) in a non-speaking outlaw cast role. With distinctive, angular features and a taciturn screen persona, Van Cleef was typecast as minor villain and supporting player in Westerns and crime dramas. After suffering serious injuries in a car crash, Van Cleef's acting career started to decline. He achieved stardom when Leone offered him the co-leading role in For a Few Dollars More.
