Kakkonen or II divisioona is the fourth level in the league system of Finnish football and comprises 36 Finnish football teams. Until the end of 2023, Kakkonen was the third-highest level in Finland, but after the creation of new second-tier Ykkösliiga, Kakkonen also dropped down one level in the league pyramid. The new fourth-tier Kakkonen is divided to three groups, each consisting of 10 teams.
The II divisioona was introduced in 1973 and in the mid-1990s became known as the Kakkonen (Finnish for 'Number Two'; Swedish: Tvåan). Sakari Tukiainen finished the season 2014 as the top goal scorer and setting a new league record with 40 goals for the Kakkonen. Petter Meyer finished the 2015 as the top goal scorer for GrIFK with 23 goals.
