Eystein Halfdansson (Old Norse: Eysteinn Hálfdansson) was the son of Halfdan Hvitbeinn of the House of Yngling according to Heimskringla. He inherited the throne of Romerike. Ari Thorgilsson in his Islendingabok calls him Eystein Speed (usually untranslated from the original Norwegian word; "Fart"), without comment, in his king list, just naming his father and his son. Snorri does not call him by this nickname, but does give us a colorful story of his life.
Eystein died while pillaging in Varna. King Skjöld of Varna, a great warlock, arrived at the beach and saw the sails of Eystein's ships. He waved his cloak and blew into it which caused a boom of one ship to swing and hit Eystein so that he fell overboard and drowned. His body was salvaged and buried in a mound. Eystein was succeeded by his son Halfdan the Mild.
