Sidney Gerald Abel (February 22, 1918 – February 8, 2000) was a Canadian professional hockey player and later coach in the National Hockey League. His playing career spanned from the 1938–39 season until the 1953–54 season, playing for both the Detroit Red Wings and Chicago Black Hawks and was a member of three winning Stanley Cups in 1943, 1950, and 1952 with the Detroit Red Wings.
Abel's son Gerry also briefly played in the NHL, and his grandson Brent Johnson is a goaltender with the Pittsburgh Penguins.
Born in Melville, Saskatchewan, "Old Bootnose", as he was known, was the third member of the Red Wings' celebrated "Production line" along with Hockey Hall of Fame teammates Gordie Howe and Ted Lindsay. Abel won the Hart Trophy as NHL MVP in 1949. Abel was traded from the Red Wings to the Black Hawks in 1952–53, and served as a player-coach for the next two seasons. He returned to the Red Wings in 1957–58 and served as Detroit's coach through the 1969–70 season. Though his #12 was honored by the Wings, Abel wore 4, 7, 9, 12, 14, 19 and 20 throughout his career.
In the 1970s and 1980s, Abel worked as a color commentator on Red Wings radio and television broadcasts.
