Vincent Millie Youmans (September 27, 1898 – April 5, 1946) was an American Broadway composer and producer.

A leading Broadway composer of his day, Youmans collaborated with virtually all the greatest lyricists on Broadway: Ira Gershwin, Otto Harbach, Oscar Hammerstein II, Irving Caesar, Anne Caldwell, Leo Robin, Howard Dietz, Clifford Grey, Billy Rose, Edward Eliscu, Edward Heyman, Harold Adamson, Buddy DeSylva and Gus Kahn. Youmans' early songs are remarkable for their economy of melodic material: two-, three- or four-note phrases are constantly repeated and varied by subtle harmonic or rhythmic changes. In later years, however, he turned to longer musical sentences and more rhapsodic melodic lines. Youmans published fewer than 100 songs, but 18 of these were considered standards by ASCAP, a remarkably high percentage.
