Frank Mills (born June 27, 1942 in Montreal, Quebec), is a Canadian pianist and recording artist, best known for his solo instrumental hit "Music Box Dancer".

Mills grew up in Verdun, Quebec and started playing piano at the age of three. He attended McGill University for five years. He began with Engineering, switched to a B.Sc. programme, then Arts and finally studied in the Department of Music. He entertained his fraternity brothers (Delta Upsilon) with songs from ragtime to a new artist Bob Dylan. The fraternity piano had thumbtacks on every hammer and produced a unique sound. In the late 1960s Mills became a member of The Bells. He left the band in 1971 just before it had international success with the single "Stay Awhile."
