Brattahlíð (Old Norse pronunciation: [ˈbrɑttɑˌhliːð]), 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.

At the site of the main church, built after the Norse were converted to Christianity, investigators have found melted fragments of bell-metal, and foundation stones of it and other buildings remained into the 20th century, as did the remnants of a possible forge.

Brattahlíð still has some of the best farmland in Greenland, owing to its location at the inner end of Eriksfjord, which protects it from the cold foggy weather and arctic waters of the outer coast.

The exact causes of the disappearance of the Norse settlements toward the end of the 15th century remain unverified, but probably resulted from a combination of the Little Ice Age's cooling temperatures, soil erosion, abandonment by Norway after the Black Plague and political turmoils, more convenient ways for Europeans to procure furs and a mercantile eclipsing by the Hanseatic League, and competition from the Inuit moving southward.

An Old Captivity (1940) by Nevil Shute is a fictional account of an early aerial investigation of the old Norse settlement at Brattalid and of Leif Ericson's journey to North America in c 1000 AD.
