William Patrick "Foxy" Dineen (September 18, 1932 – December 10, 2016) was a Canadian professional ice hockey player and head coach.

He played in the National Hockey League (NHL) for the Detroit Red Wings and Chicago Black Hawks between 1953 and 1958.

The architect of a team in roster construction, Dineen's Aeros reached the playoffs in every season of their history and won the Avco World Trophy twice.

After 1958, however, he spent the rest of his playing career in the minor leagues with various teams including the Buffalo Bisons, Cleveland Barons, Rochester Americans, Quebec Aces, Seattle Totems, and the Denver Spurs.

He spent six years behind the bench of the Houston Aeros of the World Hockey Association—the entirety of the team's existence—where he coached Gordie Howe for four seasons and won two championships.
