In Norse mythology, Gunnr or Guðr is one of the valkyries. The name means "battle" and is cognate with the Old English word "gúð".
The earliest attestation of the name is on the Rök Stone where it occurs as part of a kenning for wolf:
I say this the twelfth, where the horse of Gunnr sees fodder on the battlefield, where twenty kings lie...
In Snorri's Edda Gunnr is singled out along with Rota and Skuld as one of the valkyries who always ride out to choose the slain and decide battles:
Guðr ok Róta ok norn in yngsta, er Skuld heitir, ríða jafnan at kjósa val ok ráða vígum.
Gunnr is also mentioned in the Völuspá:
And in Darraðarljóð:
No individual characteristics of Gunnr are known to us and she does not appear as a character in any extant myth.
