Harold William Peel (June 21, 1879 – November 28, 1944[1]) was a Canadian early professional ice hockey player with the Pittsburgh Keystones of the Western Pennsylvania Hockey League.

Harry Peel was one of the first openly professional hockey players.

As a result, both Canadian and U.S. officials disallowed all amateur teams to play against the Keystones and Peel's amateur status was revoked by the Ontario Hockey Association.

As a result, the league expanded to four teams by adding the Pittsburgh Victorias, and openly enticed the best talent it could, including future Hockey Hall of Fame members Hod and Bruce Stuart from the Quebec Bulldogs, Alf Smith from the Ottawa Hockey Club and Riley Hern from the Stratford Legionnaires.

Peel died in November 1944 and is buried at Mount Pleasant Cemetery and Crematorium in his hometown of London, Ontario.
