The 1901–02 FA Cup was the 31st staging of the world's oldest association football competition, the Football Association Challenge Cup (more usually known as the FA Cup). Sheffield United won the competition for the second time, beating Southampton 2–1 in the replay of the final at Crystal Palace. The first match had finished 1–1.
Matches were scheduled to be played at the stadium of the team named first on the date specified for each round, which was always a Saturday. If scores were level after 90 minutes had been played, a replay would take place at the stadium of the second-named team later the same week. If the replayed match was drawn further replays would be held at neutral venues until a winner was determined. If scores were level after 90 minutes had been played in a replay, a 30-minute period of extra time would be played.
Calendar
The format of the FA Cup for the season had a preliminary round, five qualifying rounds, an intermediate round, three proper rounds, and the semi-finals and final.
The ten matches were played on 14 December 1901. Two matches went to replays which were played during the following midweek. Oxford City was the recipient of the walkover caused by the withdrawal of New Brighton Tower.
The matches were played on Saturday 25 January 1902. Seven matches were drawn, with the replays taking place in the following midweek. Two of these then went to a second replay the following week.
The semi-final matches were played on Saturday 15 March 1902. Sheffield United and Derby County drew their tie and had to replay it; this next match also finished in a draw, and so a second replay was played a week later. Sheffield United eventually won and went on to meet Southampton in the final.
