Albert Edward Harrison Cox (24 June 1917 in Treeton, Rotherham – April 2003) was a footballer who played as a left-back for Sheffield United and Halifax Town.
He made his league debut against Blackpool at Bramall Lane on 20 February 1936, in a 1–0 win.
In 1936, Sheffield United reached the FA Cup semi-finals, where they met fellow Second Division side Fulham.
Regular left-back, Charlie Wilkinson was injured and unavailable to play in the semi-final, so the inexperienced Cox took his place.
Although World War II interrupted his career, Cox played on for several seasons after hostilities had ended, and became one of the most consistent left-backs in the Football League.
