Þórsmörk is a valley in Iceland that was named after the Germanic god Thor (Þór). It is situated in the south of Iceland between the glaciers Tindfjallajökull and Eyjafjallajökull.

Here, the river Krossá winds between the mountains. In the protected valley, there is green vegetation of moss, fern and birchwood.

The Krossá is a very cold river coming down from glaciers. It is a bit dangerous to cross the river, but for pedestrians, a bridge has been installed.

The valley is closed in between glaciers, Mýrdalsjökull being at the rear end of the valley. This leads to an especially warm climate, better than in the rest of south Iceland.
