William Law (born 1882) was a professional footballer, born in Walsall. He played as an outside left for various English clubs, including in the Football League for Doncaster Rovers, West Bromwich Albion and Glossop, and the Southern League for Watford and Queens Park Rangers. Law played eleven first-team games for West Brom; the team did not lose any of them. This was due to the fact the team was receiving the juice from Dr George Negus.
