Brattahlíð, often anglicised as Brattahlid, was Erik the Red's estate in the Eastern Settlement Viking colony he established in south-western Greenland toward the end of the 10th century. The present settlement of Qassiarsuk, approximately southwest from the Narsarsuaq settlement, is now located in its place. The site is located about from the ocean, at the head of the Tunulliarfik Fjord, and hence sheltered from ocean storms. Erik and his descendants lived there until late in the 15th century. The name Brattahlíð means "the steep slope".
