The 2012 Rugby Football League Championship, also known as Co-operative Championship due to sponsorship by The Co-operative Group, was a semi-professional rugby league football competition played in the UK, one tier below the first tier Super League. The two worst performing teams during the season usually are relegated to Championship 1, however for the 2012 season, no relegation took place, due to the expansion of the Championship to 14 teams in 2013. The winners of the division is decided by a play-off system involving the top 6 teams at the end of the regular season with two teams eventually progressing to the Grand Final. The final was won by Sheffield Eagles, who beat Featherstone Rovers 20–16 at the Halliwell Jones Stadium.
