Kenneth Macgowan (November 30, 1888 – April 27, 1963) was an American film producer. He won an Academy Award for Best Color Short Film for La Cucaracha (1934), the first live-action short film made in the three-color Technicolor process.
Born on November 30, 1888 in Winthrop, Massachusetts, Macgowan began his career as a drama critic. He wrote many books on the modern theater including The Theatre of Tomorrow (1921), Continental Stagecraft (1922) with Robert Edmond Jones, Masks and Demons (1923) with Herman Rosse, and Footlights Across America (1929). In 1922, he ran the Provincetown Playhouse as its producer, with Eugene O'Neill and Robert Edmond Jones as business partners. His close relationship with O'Neill lasted their lifetimes.
In 1928 he moved to Hollywood, California to become a story editor for the newly formed RKO Radio Pictures and quickly became an assistant producer. By 1932, Macgowan had become a film producer for RKO, including Little Women (1933), starring Katharine Hepburn, Joan Bennett, Frances Dee and Jean Parker as the March sisters.
