The 1970–71 season was Manchester United's 69th season in the Football League, and their 26th consecutive season in the top division of English football. In a pre-season competition United participated in the Watney Cup, which was contested by the teams that had scored the most goals in each of the four divisions of the Football League the previous season who had not been promoted or admitted to one of the European competitions. United's best chance of success came in the League Cup, but they were beaten by Third Division side Aston Villa in the semi-finals.
