"I'm a Boy" is a 1966 rock song written by Pete Townshend for the Who. The song was originally intended to be a part of a rock opera called Quads, which was to be set in a future in which parents can choose the sex of their children. The idea was later scrapped, but this song survived and was later released as a single.
