Alan James Campbell (born 21 January 1948) is a Scottish former professional footballer who played as a central midfielder.
The club were only able to sign Campbell on amateur terms, creating a fake job for him at a sporting goods store and paying his accommodation plus £5 a week.
In 1965, Bob Stokoe was appointed manager of the club and handed Campbell his professional debut in the Second Division, on the opening day of the 1965–66 season in a 4–2 defeat to Bolton Wanderers, at the age of 17.
He was a midfield ever-present in the promotion winning side of 1971/72 in all competitions, (the only member of the squad to achieve this milestone) as Birmingham finished second in the old Division 2 to win promotion to Division 1 for the first time since 1965, reaching the FA Cup Semi-Final in the same season, only to lose 3–0 to eventual winners Leeds United F.C.
The following season 1975/76, after the departure of manager Freddie Goodwin (footballer, born 1944), Campbell struggled for selection, making his last appearance in an FA Cup tie at Portsmouth F.C.
