1990–91 West Ham United F.C. season

Billy Bonds in his first full season as manager guides West Ham back to the top flight of The Football League as the team finishes 2nd in the Second Division behind Oldham Athletic. Oldham were the season's top scorers in the division with 83 goals.

West Ham finished the season with the meanest defence, conceding 34 goals. The second meanest defence belonged to a 7th place Middlesbrough F.C. team, containing Colin Cooper and Tony Mowbray, which conceded 47 goals. West Ham's two games against Middlesbrough ended in 0-0 draws.

They finished one point behind champions Oldham Athletic, and also enjoyed their best FA Cup run since the triumph of 1980, reaching the semi-finals where they were beaten 4–0 by Nottingham Forest, denying them a Wembley final with local rivals Tottenham Hotspur who went on to win the trophy.

Trevor Morley was West Ham's leading scorer for 1990-91, with 12 goals in the league and 17 in all competitions, while Frank McAvennie showed full fitness after a long term injury by scoring 10 goals in the league (11 in all competitions) to finish the campaign as the club's second top scorer.
