That's Entertainment! III is a 1994 American compilation film released by Metro-Goldwyn-Mayer to celebrate the studio's 70th anniversary. It was the third and final series of retrospectives that began with the first That's Entertainment! (1974) and That's Entertainment, Part II (1976).

Unlike the previous two films, the third installment "focuses on outtakes, unfinished numbers and behind-the-scenes glimpses of the old musicals."

Hosts for the film were Gene Kelly (in his last film appearance), June Allyson, Cyd Charisse, Lena Horne, Howard Keel, Ann Miller, Debbie Reynolds, Mickey Rooney, and Esther Williams, making her first appearance in a theatrical film in more than 30 years. That's Entertainment! III had a limited theatrical release in 1994. According to film historian Robert Osborne, writing for The Hollywood Reporter at the time, the film did "pleasant business" at New York's Ziegfeld Theatre.
