The 1945–46 FA Cup was the 65th season of the world's oldest footballcup competition, the Football Association Challenge Cup, generally known as the FA Cup, and the first to be held after the Second World War. Derby County were the winners, beating Charlton Athletic 4–1 after extra time in the final at Wembley, London. The tournament witnessed a disaster in the sixth round when, during the second leg of the Bolton–Stoke City tie, 33 people were crushed to death in the Burnden Park disaster. For the only time in the history of the competition, all matches from the First Round Proper up to and including the Sixth Round Proper were played over two legs, the first leg being played at the stadium of the team named first on the date specified for each round, which was always a Saturday. In the first and second rounds proper, the second leg was played on the following Saturday; from the third round onwards, it was played during the week following the first leg. If aggregate scores were level after 90 minutes of the second leg had been played, a replay would take place at a neutral venue. These changes were made in order to give clubs additional revenue, as the Football League would not resume normal play until the autumn of 1946.
The first leg matches were played on Saturday, 8 December 1945 and the second legs on the following Saturday, 15 December 1945. No replays were necessary.
