Harold Percival "Whipper" Watson (May 6, 1923 – November 19, 2002) was a Canadian professional ice hockey left wing who played for the Brooklyn Americans, Detroit Red Wings, Toronto Maple Leafs, and Chicago Black Hawks, winning five Stanley Cups over a 14-year career in the National Hockey League.

In 1941, at age 18, Watson turned professional with the Brooklyn Americans in the NHL in what would be the team's final season.

He was selected by the Detroit Red Wings in an intraleague draft and played there in 1942–43, winning his first Stanley Cup.

Watson then joined the Royal Canadian Air Force as World War II escalated.

After a two-year break from the NHL, Watson rejoined the Red Wings after the war for one season and was traded to the Toronto Maple Leafs on September 21, 1946, for Billy Taylor.
