The 2011 Norwegian First Division season (known as Adeccoligaen for sponsorship reasons) began play on 3 April 2011 and ended on 30 October 2011.
The clubs relegated from the 2010 Premier League were Hønefoss (after relegation play-offs), Kongsvinger and Sandefjord. Asker, HamKam, Hødd, and Randaberg were promoted from the 2010 Second Division.
Following an extended period of financial distress, Lyn withdrew from the league in 2010.Follo did not finish their licensing application for the 2011 season before the time limit of 15 September 2010, and were thus relegated at the end of the 2010 season even though they finished 12th, outside of the relegation zone. As a result of this the 13th placed team, Sandnes Ulf, avoided relegation.Tromsdalen and Moss were the remaining two teams relegated to the 2011 Second Division.
At the end of the season, the two best teams will be promoted to the 2012 Premier League, while the 4 worst placed teams will be relegated to the 2012 Second Division. There will not be a two-legged promotion playoff this season.
