The 1971–72 FA Cup was the 91st season of the world's oldest football cup competition, the Football Association Challenge Cup, commonly known as the FA Cup. Leeds United won the competition for the first time, defeating holders Arsenal 1–0 in the final at Wembley, London.

Several records were set during this FA Cup season. This was the third year in which the losing semi-finalists were required to compete in a "match for third place"; following a goalless 90 minutes, Birmingham City beat Stoke City in a penalty shootout, the first time this method had been used to determine the result of an FA Cup match.

In the first round proper, Ted MacDougall's nine goals for AFC Bournemouth as they beat Margate 11–0 remains the record for goals scored in a match in the FA Cup proper. The fourth qualifying round tie between Alvechurch and Oxford City became the longest FA Cup tie ever, lasting a total of eleven hours before Alvechurch won the fifth replay 1–0.

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 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.

Qualifying rounds Most participating clubs that were not members of the Football League competed in the qualifying rounds to secure one of 28 places available in the first round.

Those appearing in the competition proper for the first time were Ellesmere Port Town, Redditch United, Alvechurch, Basingstoke Town and Witney Town. Rossendale United was appearing at this stage for the first time since predecessor outfit Rossendale FC had entered the competition in 1887–88. Of the others, Frickley Colliery, Maidenhead United and Bridgwater Town had last qualified for the first round in 1963–64 and Dover had last done so in 1960–61.

Results

First round proper At this stage the 48 clubs from the Football League Third and Fourth Divisions joined the non-league clubs who came through the qualifying rounds. To complete the round, four additional non-league clubs received byes to this stage. Telford United and Hillingdon Borough were the finalists from the previous season's FA Trophy competition, while Skelmersdale United and Dagenham were the finalists from the previous season's FA Amateur Cup.

Matches were scheduled to be played on Saturday, 20 November 1971, although the Aldershot-Alvechurch match was delayed until 24 November because Alvechurch's fourth qualifying round tie against Oxford City had gone to a fifth replay which took place on 22 November, two days after the date set for the first round ties. Also of particular note, Ted MacDougall set a goalscoring record for the FA Cup proper with nine goals for Third Division AFC Bournemouth as they beat Margate of the Southern League 11–0.

Nine drawn matches in this round were settled by a single replay.

Third round proper The 44 First and Second Division clubs entered the competition at this stage. The matches were scheduled for Saturday, 15 January 1972; the tie between Newcastle United and Hereford United at Newcastle was twice postponed because of a waterlogged pitch on which snow had fallen. Ten matches were drawn, each of which was settled by a single replay. The replay between Hereford and Newcastle, also the subject of several postponements and eventually played on the day scheduled for the fourth round ties, was voted "best FA Cup tie ever" in a 2007 poll hosted in The Observer newspaper. It was the first time a First Division club had been eliminated from the competition by non-league opponents since Sunderland's shock loss to Yeovil Town in 1948–49.
