Þrúðr (Old Norse "strength"), sometimes anglicized as Thrúd or Thrud, is a daughter of the major god Thor in Norse mythology. Þrúðr is also the name of one of the valkyries who serve ale to the einherjar in Valhalla (Grímnismál, stanza 36). The two may or may not be the same figure.
Þrúðr is attested in the following sources:
Poetic Edda 
Prose Edda 
The Prose Edda bookt Skáldskaparmál (4) tells that Thor can be referred to by the kenning "father of Þrúðr" ("faðir Þrúðar"). Eysteinn Valdason uses it in his poem about Thor (2). The Skáldskaparmál (21) adds that her mother is Sif.
In Bragi Boddason's Ragnarsdrápa, the Jötunn Hrungnir is called "thief of Þrúðr" (Þrúðar þjófr). But there is no direct reference to this myth in any other source. The Skáldskaparmál (17), in which Snorri relates the fight between Thor and Hrungnir, mentions a very different cause, and Þjóðólfr of Hvinir's Haustlöng only describes the fight without giving the reason for it. This poem depicts two mythological scenes painted on a shield, the first being Iðunn's abduction by the giant Þjazi. Margaret Clunies Ross suggested that the two episodes might be complementary, both dealing with the abduction of a goddess by a giant, its failure and the death of the abductor. Another kenning may allude to this myth: in Eilífr Goðrúnarson's Þórsdrápa (18), Thor is called "he who longs fiercely for Þrúðr" (þrámóðnir Þrúðar).
Karlevi Runestone 
The name Þrúðr could be used in kennings for chieftains as exemplified on the Karlevi Runestone. The name is also used in kennings for women. Ormr Steinþórsson, for instance, uses in his poem about a woman (4) the kenning "hrosta lúðrs gæi-Þrúðr", which, according to Anthony Faulkes, can be rendered into "keeper of the malt-box (mash-tub) or ale-vessel".
