1926–27 FA Cup

The 1926–27 FA Cup was the 52nd staging of the world's oldest football cup competition, the Football Association Challenge Cup, commonly known as the FA Cup. Welsh club Cardiff City won the competition for the first time, beating Arsenal 1–0 in the final at Wembley. As of 2024, it is the only FA Cup title won by a club from outside England.

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 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.
