Stephen George Bull MBE (born 28 March 1965) is an English former professional footballer who is best remembered for his 13-year spell at Wolverhampton Wanderers. He played there from 1986 until his retirement from playing in 1999, and holds the club's goalscoring record with 306 goals, which included 18 hat-tricks for the club.

He was capped 13 times for the England team between 1989 and 1990, scoring four goals.

Bull was born in Tipton and started school in September 1969 at Wednesbury Oak Primary School and moved up to Willingsworth High School in September 1976, by which time he was excelling in school football teams. The junior teams he played for included Ocker Hill infants, Red Lion and Newey Goodman. He left school in 1981 to join non-league Tipton Town. During this time he also held down a succession of factory jobs in addition to playing local league games.

He began his professional career, aged 19, after being recommended to West Bromwich Albion in 1984 by his Tipton Town manager Sid Day, who also worked as a scout for the Baggies. After initially having to train with the club's youth ranks, he was quickly offered a pro contract and moved into first team contention. He made his senior debut on 23 October 1985, replacing Garth Crooks in a 2–1 Full Members Cup win against Crystal Palace. He made his league debut as a substitute against QPR, away, on 12 April 1986 (lost 1–0), and his full debut at home to Sheffield Wednesday on 22 April (drew 1-1); they were his only league appearances that season and only appearances in top flight football.

Bull played three Second Division games for Albion after they were relegated in 1986, scoring twice, and also scored one goal in two League Cup appearances for the club. Bull knew it would be difficult to break the Crooks/Varadi partnership, so was prepared to drop to the bottom tier in search of first team football. In November 1986, he was sold to local rivals Wolverhampton Wanderers, along with Andy Thompson, for £65,000 where he remained until the end of his professional career in 1999, being one of Wolves' most loyal players.

Bull's debut for Wolves, then languishing in the Fourth Division, was against Wrexham on 22 November 1986. His first goal for the club came on 2 December 1986 in the Associate Members' Cup as Wolves beat Cardiff City 1–0 at Ninian Park.

In over 13 years at Wolves, Bull broke four of the club's goalscoring records. He became their all-time leading goalscorer with 306 goals in competitive games (250 of them in the Football League, also a club record) and became their highest goalscorer in a single season when he scored 52 goals in competitive games during the 1987–88 season. Bull also scored a club record of 18 hat-tricks - the first of them against Hartlepool United in a 4-1 Fourth Division home win on 9 May 1987, the last on 17 August 1996 in a 3-1 Division One away win over Grimsby Town.

Bull's first season at the club saw him score a total of 19 goals for Wolves - 15 of them in the Fourth Division, in which they finished fourth - although they lost out on promotion after being beaten by Aldershot in the playoffs.
