Eyfura was a princess in Norse mythology, who married Arngrim and had twelve sons. In all accounts, her twelve sons would be slain by the Swedish champion Hjalmar and his friend Orvar-Odd. According to the Hervarar saga, versions U and H, she was the daughter of Svafrlami, the king of Gardariki. Her father was slain by Arngrim who took Eyfura as his wife by force. According to version R, her father's name was Sigrlami and he gave Eyfura to Arngrim in recompense for his services as war-chief.
