Harry Rigby (c. 1925 – January 17, 1985) was an American theatre producer and writer. Born in Pittsburgh, Pennsylvania, Rigby joined forces with Jule Styne and Alexander H. Cohen to produce the short-lived 1951 Hugh Martin musical Make a Wish as his first Broadway outing. Two years later he enjoyed greater success with John Murray Anderson's Almanac, a revue with an eclectic cast that included Harry Belafonte, Polly Bergen, Hermione Gingold, Billy Wolfe, Orson Bean, Kay Medford, Larry Kert, and Tina Louise. Rigby died in New York City.
