Jötunheimr (often anglicized Jotunheim) is the world of the giants (two types: rock and frost, collectively called Jotuns) in the Norse Mythology. From here they menace the humans in Midgard and the gods in Asgard (from whom they are separated by the river Iving). Gastropnir, home of Menglad, and Thrymheim, home of Thiazi, were both located in Jotunheim, which was ruled by King Thrym. Glæsisvellir was a location in Jotunheim, where lived the giant Gudmund, father of Höfund.

Jotunheimen is also the name of a large mountain range in Norway. Its highest peak, Galdhøpiggen (2469 metres) is the highest mountain in Scandinavia.
