Þrúðr (Old Norse: [ˈθruːðz̠], "strength"), sometimes anglicized as Thrud or Thrúd, is a daughter of the major god Thor and the goddess Sif 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 Poetic Edda poem Alvíssmál, in which a dwarf, Alvíss, claims to be engaged to Thor's daughter, maybe about Þrúðr, but the daughter is not named.
