Agnarr Geirröðsson is the son of King Geirröðr in Norse mythology. Agnarr is solely attested in the poem Grímnismál in the Poetic Edda, the latter compiled in the 13th century from earlier traditional sources. In Grímnismál he is described as aiding Odin, disguised as Grímnir, to escape from Geirröðr's torture.
