The 2011 elections to Nottingham City Council were held on 5 May 2011 to elect all 55 members to the council.
The previous election was held in 2007 and the results were: Labour 42, Conservatives 7, Liberal Democrats 6. At the time of the 2011 election one Labour councillor, Mick Newton, had left the party and was an independent councillor. This left Labour with 41 councillors at the time of the election.
No ward boundary changes took place between the 2007 and 2011 elections.
The result of the election was notable for completely wiping-out the Liberal Democrats in Nottingham. The Conservative Party lost two seats, whilst Labour strengthened their position.
A total of 55 councillors were elected from 20 wards in the city.
The expected declaration time was 4am on 6 May.
