The 2011–12 Nemzeti Bajnokság I, also known as NB I for short, was the 110th season of top-tier football in Hungary. The league was officially named OTP Bank Liga for sponsorship reasons.[2] The season began on 15 July 2011[3] and ended on 27 May 2012.[4] Videoton were the defending champions, having won their first Hungarian championship at the end of the 2010–11 season.
Szolnok and MTK finished the 2010–11 season in the bottom two places of the table and thus were relegated to their respective NB II divisions. MTK ended a 16-year stay in the top league, while Szolnok were relegated after just one year in the league.
The two relegated teams were replaced with the champions of the two 2010–11 NB II groups, Diósgyőr of the East Group and Pécs of the West Group. Diósgyőr made their immediate comeback to the league, while Pécs returned to the competition after an absence of four seasons.
