Calvin Lockhart (born Bert McClossy Cooper; October 18, 1934 – March 29, 2007) was a Bahamian–American stage and film actor.

He spent one year at the Cooper Union School of Engineering, then left to pursue an acting career.

In 1960, Lockhart made his Broadway debut, playing a gang leader in The Cool World (a dramatization of Warren Miller's novel of the same name), which closed after just two performances.

Lockhart's first lead role in a film was in Halls of Anger (1970), playing a former basketball star who becomes vice-principal of an inner-city high school to which 60 white students are being moved.

An article in The New York Times that year described Lockhart as having "matinee-idol looks" with "chiseled-out-of-marble features" and "skin the color of brown velvet".
