In Norse mythology, Þjazi was a jötunn. He was a son of the jötunn Ölvaldi, brother of Iði and Gangr, and the father of Skaði. His most notable misdeed was the kidnapping of the goddess Iðunn, which is related in both the Prose Edda and the skaldic poem Haustlöng.
Iðunn is carried off by Þjazi in this artwork by Harry George Theaker, 1920.

A jötunn is a type of being in Germanic mythology. In Norse mythology, they are often contrasted with gods and other non-human figures, such as dwarfs and elves, although the groupings are not always mutually exclusive. The entities included in jötunn are referred to by several other terms, including risi, þurs and troll if male and gýgr or tröllkona if female. The jötnar typically dwell across boundaries from the gods and humans in lands such as Jötunheimr.
