Medium Cool is a 1969 American drama film written and directed by Haskell Wexler and starring Robert Forster, Verna Bloom, Peter Bonerz, Marianna Hill and Harold Blankenship. It takes place in Chicago in the summer of 1968. It was notable for Wexler's use of cinéma vérité-style documentary filmmaking techniques, as well as for combining fictional and non-fictional content.

Haskell Wexler was an American cinematographer, film producer, and director. Wexler was judged to be one of film history's ten most influential cinematographers in a survey of the members of the International Cinematographers Guild. He won the Academy Award for Best Cinematography twice, in 1966 and 1976, out of five nominations. In his obituary in The New York Times, Wexler is described as being "renowned as one of the most inventive cinematographers in Hollywood."
