Halfdan Long-Leg (Old Norse: Hálfdan háleggur, Norwegian: Halvdan Hålegg) was a Viking-Age warrior who lived in the latter half of the 9th century. He was the son of King Harald Fairhair and a Sami woman named Snofrid Svasadottir.
Snorri Sturluson in Heimskringla states that Halfdan was one of Harald's many sons who were involved in a power struggle with one another. Halfdan and his brother Gudrød Ljome were responsible for murdering Rognvald Eysteinsson and 60 of his men by burning them inside of a structure. Upon learning of this event, Harald flew into a rage and sent out a great force against Gudrød who was then banished. Rognvald's son Torf-Einarr performed the Blood eagle ritual on Halfdan in retaliation after a battle. Harald made Rognvald's son Thorirm Earl of Møre and gave his daughter Alof to him in marriage.
