1989–90 Associate Members' Cup

The 1989–90 Associate Members' Cup, known as the 1989–90 Leyland DAF Cup, was the ninth staging of a secondary football league tournament, and the seventh staging of the Associate Members' Cup, a knock-out competition for English football clubs in the Third Division and the Fourth Division. The winners were Tranmere Rovers and the runners-up were Bristol Rovers.

The competition began on 7 November 1989 and ended with the final on 20 May 1990 at Wembley Stadium.

In the first round, there were two sections split into eight groups: North and South. In the following rounds each section gradually eliminates teams in knock-out fashion until each has a winning finalist. At this point, the two winning finalists faced each other in the combined final for the honour of the trophy.
