Clarence Gaskill (b. February 2, 1892 in Philadelphia, Pennsylvania; † April 29, 1947 in Fort Hill, New York) was a U.S. songwriter, lyricist, pianist, and music publisher whose best-known songs include "Minnie the Moocher" (1929) and "Prisoner of Love" (1931).
Gaskill attended St. John's School and Friends School in Philadelphia; he had additional music lessons with his mother and private tutors. At sixteen he performed as a pianist in a hometown theater, and at 21 he founded a music publishing company. During World War I, he served as a machine gunner and was awarded the Purple Heart. In the postwar years, he toured in vaudeville as Melody Monarch. Beginning in the early 1920s, he was primarily a songwriter; he worked with Jimmy McHugh, Cab Calloway, Irving Mills, Leo Robin, and Duke Ellington, among others. Among the best-known songs Gaskill was involved in are "I Can't Believe That You're in Love with Me," "Another Perfect Day Has Passed Away," "Doo-Wacka-Doo," "Swanee River Rhapsody," "Strange Interlude," "I Don't Mind Being All Alone (When I'm All Alone with You) " and "Still I Love Her."
