The 2010–11 National Conference League was the 26th season of the National Conference League, the top league for British amateur rugby league clubs, and was the final season that the league was played in the winter.
The Premier Division featured three new clubs:
Division One featured six new clubs:
Widnes St Maries resigned from the league mid-season; their record was expunged.[1]
Division Two featured four new clubs:
West Bowling were forced to withdraw at the end of the season due to the league being switched to a summer competition and their pitch not being available during the cricket season.[2]
Between August 2011 and November 2011, a short transitional season was played in preparation for the switch to a summer competition in 2012. Two new teams, Askam and Widnes West Bank, joined the competition, increasing the number of teams to 40. The league was split into eight groups of five teams based in geographical location (due to the subsequent withdrawal of West Bowling, Group G only consisted of four teams). The play-offs were contested by the eight group winners. The league champions were Hunslet Warriors, who defeated Wigan St Patricks 18–14 in the play-off final after extra time.[3]
