The 2017–18 FA Cup was the 129th season of the world's oldest association football knockout competition; The Football Association Challenge Cup, or FA Cup for short. As in the previous year, 762 clubs were accepted for the competition.
The competition commenced on 12 August 2017 with the Extra Preliminary Round and concluded on 12 May 2018 with the Final, held at Wembley Stadium. The final was contested by 2017 winners Manchester United and 2013 winners Liverpool. Originally, the winners were to qualify for the play-off round of the 2010–11 UEFA Europa League. However, as Manchester United won the 2017–18 Premier League and the League Cup (and did not need the FA Cup winners' berth), and Liverpool qualified for the UEFA Champions League through their fourth-place finish, the berth was given to Manchester City, the seventh-placed team in the Premier League. Manchester United won 3-0 in the final to retain the trophy.
