Kolmården () is a long and wide densely forested rocky ridge that separates the Swedish provinces of Södermanland and Östergötland, two of the country's main agricultural areas, from each other, and in historic times, along with Tylöskog and Tiveden, formed the border between the land of the Swedes and the land of the Geats.

History

In early medieval times it was seen as a major obstacle in land travel between the regions, and so the Baltic Sea was largely used instead. Together with the extensive forests of Tiveden and Tylöskog to its west, Kolmården formed a major impediment for travel between the Swedes in Svealand to the north and the Geats in Götaland, which caused peaceful and warlike interaction to be conducted by water.

In the Icelandic text Sögubrot af nokkrum fornkonungum, Kolmården between Svealand and Östergötland is described as the border between Sweden and Östergötland (..). It also appears as Mirkwood in some editions of Sögubrot,
