Geirröðr
Geirröðr is a jötunn in Norse mythology. He is the father of the jötnar Gjálp and Greip, who are killed by the thunder-god Thor, and the possible father of the jötnar Eistla, Angeyja, Ulfrún, Eyrgjafa, Imd, Atla and Járnsaxa.
Geirröðr is mentioned in the skaldic poem Þórsdrápa, written by Eilíf Godrúnarson, itself cited in Skáldskaparmál where it is preceded by Snorri Sturluson's account of the myth, and in Gesta Danorum by Saxo Grammaticus.
Saturn's moon Geirrod is named after him.

Prose Edda
In Skáldskaparmál, Loki is flying in Frigg’s hawk coat to Geirrödargardar, the abode of the giant Geirröðr, when he is captured by the latter and locked in a chest for three months. To redeem his life, Loki agrees to bring Thor to Geirröðr's place without his belt of strength and hammer. On their way to Geirrödargardar, Thor and Loki stop at the home of the giantess Gríðr. She warns Thor about Geirröðr's plan and equips him with a new belt of strength, a pair of iron gloves, and a staff named Grídarvöl. Arriving at Geirrödargardar, Thor is eventually challenged to a game by Geirröðr. The giant throws a piece of red-hot iron at him, but Thor is able to catch it with the iron gloves. As Geirröðr tries to hide behind a pillar, Thor throws the piece of iron through the column and kills him.Viking Age
