Robert Hall Allen (11 June 1886 – 20 September 1981) was a British Army officer and an English footballer who played as a forward.
The Westminster Gazette described Allen's performance as "heavy and fast", exerting "wonderful control over the light, dry ball, dribbling in a style reminiscent of the old-time Corinthians" whilst "giving perfect passes".
Despite being signed in time for the 1914–15 season, Allen didn't play for the club due to his military commitments in World War I.
