The 2nd Division () is a semi-professional association football league for men and the third division in Denmark. It is organised by the Divisionsforeningen on behalf of the Danish Football Association (Danish FA; DBU) as part of the nation-wide Danmarksturneringen i fodbold (Herre-DM) and is positioned between the second-tier 1st Division and the fourth-tier Danish 3rd Division in the Danish football league system. Clubs in the league must meet certain criteria concerning appropriate facilities and finances. All of the 2nd Division clubs qualify for the proper rounds of the DBU Pokalen. The number of promoted and relegated clubs has fluctuated over the years. In the 2020–21 season two clubs were directly promoted to the 1st Division, while eight teams were relegated to the Denmark Series. From the 2021–22 season, it was changed to two promotion spots and two relegation spots. A third-tier league under the auspices of the Danish FA was introduced to the nation-wide league structure in 1936, beginning with two divisions of four clubs each in the 1936–37 season. Due to World War II, the league was placed on hiatus for five years until its reintroduction as a single division with 10 clubs in 1945. In the 1966 season, the league was expanded to include two divisions, coinciding with the dissolution of the Kvalifikationsturneringen and the introduction of the new fourth-tier, Denmark Series (Danmarksserien). It returned to a single division format in the 1975 season, before once again converting to a two division format in 1986, a single division in 1997 and a two division format in 2005. From 1991 to 1997 the league was played as semi-annual seasons, when the higher ranking leagues switched to an autumn-spring calendar match schedule while the lower ranking leagues continued with spring-autumn tournaments — a revisit to the same calendar schedule that had been played until 1956. In 2015–2020, the league consisted of two stages; a preliminary round split into 2–3 groups with clubs qualifying for either a promotion or relegation round. From 1936–37 and 1939–40, 1966 until 1964 and in the 1986 season, a championship final was played at the end of the season to determine the overall league winners between the west and east groups. The short lived Kvalifikationsligaen in the springs from 1992 to 1995 meant that the league's status as the third-tier in Danish football was dropped one level to temporarily become the fourth best level.
