John Francis Oscar Arpin (3 December 1936 – 8 November 2007)[1] was a Canadian composer, recording artist and entertainer, best known for his work as a virtuoso ragtime pianist.

Born in Port McNicoll, Ontario Arpin studied piano at The Royal Conservatory of Music, earning his ARCT diploma in 1953.

High Fidelity magazine said of one of his albums: "This is the best recorded collection of piano rags that I know of and is, I suspect, the most authentically performed."

His "Lyric Suite for Piano, Strings and Percussion" won first prize out of 450 entrants in the Yamaha Second International Original Concert in Tokyo.

In 2005, he was commissioned by St. Michael's Choir School (Toronto) to compose and arrange a "medley" of Christmas tunes which he titled "Yuletide on the Cool Side".
