The 2011–12 Topklasse season was the second edition of the Dutch league since its inception in 2010. A total 32 teams competed in the league: 24 from the 2010–11 Topklasse, and the remaining eight from the 2010–11 Hoofdklasse. As usual, the competition was divided into two leagues: "Saturday" and "Sunday", who differ by the day their games are usually played.
