John William Davis was a footballer who played as a forward for Port Vale and Macclesfield in the 1920s.
Davis played for Bredbury United before joining Second Division side Port Vale as an amateur in January 1920. His single appearance came at inside-right in a goalless draw with Fulham at the Old Recreation Ground on 16 April 1921. He was released, probably in 1922, and moved on to Macclesfield.
