Gunnr or Guđr is a valkyrie in Norse mythology. Her name means "battle" and is cognate with the English word "gun". No individual characteristics of Gunnr are attested and she does not appear as a character in any surviving myth.

Rök Stone

The earliest attestation of the name is on the Rök Stone where it occurs as part of a kenning for wolf:

Ţat sagum tvalfta, hvar hćstR se GunnaR etu vettvangi a, kunungaR tvaiR tigiR svađ a liggia.

Translation:

I say this the twelfth, where the horse of Gunnr sees fodder on the battlefield, where twenty kings lie...

Poetic Edda

Völuspá

Gunnr is also mentioned in Völuspá:

Sá hon valkyrjur

vítt um komnar

görvar at ríđa

til Gođţjóđar:

Skuld hélt skildi,

en Skögul önnur,

Gunnr, Hildr, Göndul

ok Geirskögul;

nú eru talđar

nönnur Herjans,

görvar at ríđa

grund valkyrjur.

And in Darrađarljóđ:

Prose Edda

In the Prose Edda Gunnr is singled out along with Róta and Skuld as one of the valkyries who always ride out to choose the slain and decide battles:

Guđr ok Róta ok norn in yngsta, er Skuld heitir, ríđa jafnan at kjósa val ok ráđa vígum.
