The 1985 Luton riot occurred before, during and after a 1984–85 FA Cup sixth-round football match between Luton Town and Millwall on 13 March 1985 at Luton Town's Kenilworth Road ground in Luton, Bedfordshire, England, United Kingdom. It was one of the worst incidents of football hooliganism during the 1980s, and led to a ban on away supporters by Luton Town which lasted for four seasons. This itself led to Luton's expulsion from the Football League Cup during the 1986–87 season. The club also began to enforce a membership card scheme, which Margaret Thatcher's government attempted to have adopted at grounds across England. Kenilworth Road was damaged, along with the surrounding area, and a year later was converted to an all-seater stadium.
