The 2012 Conference National play-off Final, known as the 2012 Blue Square Bet Premier play-off Final for sponsorship purposes, was a football match between Luton Town and York City on 20 May 2012 at Wembley Stadium in London. It was the tenth Conference National play-off Final and the first to be played at Wembley since 2010. York won the match 2–1, coming from behind after conceding to Luton in the second minute to secure promotion to Football League Two, re-entering the Football League after an eight-year absence
