1905–06 FA Cup

The 1905–06 FA Cup was the 35th staging of the world's oldest association football competition, the Football Association Challenge Cup (more usually known as the FA Cup). Everton won the competition for the first time, beating Newcastle United 1–0 in the final at Crystal Palace.

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.

The Crystal Palace versus Chelsea tie in the third qualifying round led to the Football Association changing the rules. The tie was scheduled to be played on 18 November 1905, and Chelsea were also obliged to play a Football League game against Burnley on the same day. Chelsea were chasing promotion from the Second Division, so they fielded a full strength side in the league and sent a reserve team to the FA Cup match. Crystal Palace won the fixture 7–1. As a result of the outcry, the Football Association amended its rules such that teams must always field their strongest side in the FA Cup.
