Ian Timothy Whitcomb (born 10 July 1941, in Woking Hospital, Woking, Surrey, England) is an entertainer, singer, songwriter, author, record producer, and actor. As part of the British Invasion, his hit song "You Turn Me On" reached number 8 on Billboard Hot 100 chart in 1965.

He has written several books on popular music, beginning with After the Ball, published by Penguin Books (Britain) and Simon & Schuster (United States) in 1972. He accompanies his singing by playing the ukulele and, through his records, concerts, and film work, has helped to stimulate the current revival of interest in the instrument. His recreation of the music played aboard the RMS Titanic in the film of that name won a Grammy Award in 1998 for package design and a nomination for Whitcomb's liner notes (Titanic: Music as Heard on the Fateful Voyage).
