The 2011–12 Czech 2. Liga is the 19th season of the Czech Second Division, the second tier of the Czech football league. The season began on 5 August 2011 and concluded on 26 May 2012. The winter break commenced after 19 November 2011 and the league restarted on 10 March 2012. FK Ústí nad Labem secured promotion to the Czech First League on 12 May 2012. However, due to their stadium, which did not comply with league regulations, Ústí were not granted a license to play in the following season's Czech First League. The promotion place therefore went to fourth-placed Brno.
