The 1987–88 FA Cup was the 107th season of the world's oldest knockout football competition, The Football Association Challenge Cup, or FA Cup for short. The competition was won by Wimbledon F.C.'s Crazy Gang who defeated league champions Liverpool through a headed goal by Lawrie Sanchez, thus denying Liverpool the double. They would be one of three clubs other than Manchester United, Arsenal, Chelsea and Liverpool to win the trophy in the following 20 years (the others being Everton and Tottenham Hotspur) before Portsmouth's victory in the 2008 final. This was Wimbledon's only FA Cup title during its lifetime.
