The 2003–04 FA Cup was the 123rd staging of England and the world's oldest football competition, the FA Cup. The competition began on 23 August 2003, with the lowest-ranked of the entrants competing in the Extra Preliminary round. In the Third Round, the clubs from the Premiership and Division One competed in the competition for the first time.
The semi-finals were staged at neutral venues and, like the final, would not be replayed in the event of a draw. The competition culminated with the cup final at the Millennium Stadium, Cardiff for a fourth year in a row, since Wembley Stadium was still in the rebuilding process. The cup was won by Manchester United for a record 11th time, with a 3–0 victory over Millwall from Division One.
