Rupert Holmes (born February 24, 1947) is an American-British composer, singer-songwriter, musician and author of plays, novels and stories. He is best known for his number one pop hit "Escape" (subtitled "The Piña Colada Song") in 1979, his Tony Award winning musical Drood (originally The Mystery of Edwin Drood) and his more recent Broadway musical Curtains.

Rupert Holmes made his professional debut as a playwright with the musical The Mystery of Edwin Drood, later known as Drood, in 1985. Holmes was encouraged to write a musical by Joseph Papp and his wife after they attended one of Holmes's cabarets in 1983. The result, loosely based on the Charles Dickens unfinished novel, and inspired by Holmes's memories of English pantomime shows he attended as a child, would earn Holmes Tony Awards for both book and score, as well as Drama Desk Awards (for book, music, and lyrics), and various other honors. Holmes also orchestrated Drood himself, making him one of the few Broadway composers to write his own orchestrations.
