Hymir (Old Norse: Hymir) is a powerful giant who features as the primary antagonist in the Eddic poem Hymiskviða. In Hymiskviða, Thor and Týr travel to Hymir’s hall to obtain a great cauldron large enough to brew ale for all the gods. The journey involves a series of contests, including the famous episode in which Thor nearly catches the Midgard Serpent Jörmungandr on a fishing line baited with an ox head, before Hymir cuts the line in fear. Thor kills Hymir and the pursuing giants to escape with the cauldron.

Hymir is named in Hymiskviða as Týr’s father — ‘the father of Týr’ is an explicit phrase in the poem, providing the primary source basis for Hymir’s paternity of Týr, which stands in direct contradiction to Gylfaginning’s statement that Týr is a son of Odin.
