In Norse mythology, Helblindi ("Hel-blinder" or "All-blind" - possible to render "Death-defier") is a jötunn, brother of Loki and Býleistr and possibly son of Fárbauti ("cruel-striker") and his wife Laufey. Helblindi is also a heiti used to describe Odin.
Though not directly attested in any original source, scholars have considered Helblindi to be a son of Fárbauti. However, his exact role in the ancient mythic complex surrounding Loki's family remains unclear.
