In Norse mythology, Geri and Freki (Old Norse, both meaning "the ravenous" or "greedy one") are two wolves which are said to accompany the god Odin. They are attested in the Poetic Edda, a collection of epic poetry compiled in the 13th century from earlier traditional sources, in the Prose Edda, written in the 13th century by Snorri Sturluson, and in the poetry of skalds. The pair has been compared to similar figures found in Greek, Roman and Vedic mythology, and may also be connected to beliefs surrounding the Germanic "wolf-warrior bands", the Úlfhéðnar.
The names Geri and Freki have been interpreted as meaning either "the greedy one" or "the ravenous one". The name Geri can be traced back to the Proto-Germanic adjective *geraz, attested in Burgundian girs, Old Norse gerr and Old High German ger or giri, all of which mean "greedy". The name Freki can be traced back to the Proto-Germanic adjective *frekaz, attested in Gothic faihu-friks "covetous, avaricious", Old Norse frekr "greedy", Old English frec "desirous, greedy, gluttonous, audacious" and Old High German freh "greedy".John Lindow interprets both Old Norse names as nominalized adjectives.Bruce Lincoln further traces Geri back to a Proto-Indo-European stem *gher-, which is the same as that found in Garmr, a name referring to the hound closely associated with the events of Ragnarök.
