William Watson (born 4 December 1949) is a Scottish former footballer, who played as a defender.
He played sparingly for United, going on loan to the Miami Toros of the North American Soccer League in 1973.
In 1980, he moved to the United States and signed with the Phoenix Inferno of the Major Indoor Soccer League.
In the last season, the team was renamed the Phoenix Pride because the new Mormon ownership objected to the reference to hell.
