The 2011–12 season was the 80th season in NK Varaždin (1931–2015) history and their twenty-first in the Prva HNL. Their 11th-place finish in the 2010–11 season means it was their 21st successive season playing in the Prva HNL. While the club was reinstated to the 3. HNL for the 2103–14 season, its continued financial woes saw the then 74-year-old organisation declare bankruptcy, and cease to exist, at the end of the 2014–15 season.
