Hyrrokkin was a giantess in Norse mythology. She launched Baldr and Nanna's funeral ship because none of the gods were able to. When she pushed the boat into the water, she caused the ground to quake, greatly angering Thor. He was about to strike her dead with Mjölnir when the gods intervened on her behalf. However, in the Skáldskaparmál, she is listed as having been killed by Thor.
