1963–64 FA Cup

The 1963–64 FA Cup was the 83rd staging of the world's oldest football cup competition, the Football Association Challenge Cup, commonly known as the FA Cup. West Ham United won the competition for the first time (despite having reached the 1923 final), beating Preston North End 3–2 in the final at Wembley.

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. Some matches, however, might be rescheduled for other days if there were clashes with games for other competitions or the weather was inclement. 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 scores were level after 90 minutes had been played in a replay, a 30-minute period of extra time would be played.
