The 12th man or 12th player is a collective term for fans of sports teams in many eleven-a-side games, in particular association football or American football. As most football leagues allow a maximum of eleven players per team on the playing field at a time, referring to a team's fans as the 12th man implies that they have a potentially helpful and significant role in the game.
