The 2011–12 Druga HNL (also known as 2. HNL) was the 21st season of Croatia's second level football competition since its establishment in 1992. HNK Gorica were league champions and earned a place in Croatia's first division, which was later denied after getting their top level license revoked. Second placed NK Lučko were the only promoted team at the end of the previous season. The competition started on 19 August 2011 and ended on 20 May 2012.[1]
The league was contested by 15 teams (one less than in the previous season). Only Lučko were granted top level license, Gorica's license was revoked after appeal from Istra 1961. Third placed Pomorac unsuccessfully tried to obtain it through arbitration. Only two teams from Treća HNL were granted license for competing in the Druga HNL, but only Radnik Sesvete was promoted as Segesta didn't finish the season within top five places.
