The Western Settlement (Vestribyggð) was a group of farms and communities established by Norsemen from Iceland around AD 985 in medieval Greenland. Despite its name, the Western Settlement was more north than west of its companion and located at the head of the long Nuup Kangerlua fjord (inland from Nuuk, the present Greenlandic capital).
At its peak, the Western Settlement probably had about 1,000 inhabitants, about a fourth the size of the Eastern Settlement, owing to its shorter growing season. The largest of the Western Settlement farms was Sandnæs. Ruins of almost 95 farms have been found in the Western settlement.
Much less is known about the Western Settlement than the Eastern Settlement, as there is very little mention and no direct description of it in any of the medieval sources on Greenland. The Norse settlement was last mentioned by the traveller Ivar Bardarson, who wrote to the Bishop of Bergen to describe conditions he observed sometime between 1341–60. In his voyage to the Western Settlement, he found only vacant farms.

They have been well maintained throughout the centuries and are now a major tourist attraction as well as a UNESCO World Heritage Site. Visitors can walk around about half of the length of the walls.
The layout of the city is an even quadrilateral with a perimeter of 2,516 m. Its walls, which consist in part of stones already used in earlier constructions, have an average thickness of 3 m. Access to the city is afforded by nine gates of different periods; twin 20 m high towers, linked by a semi-circular arch, flank the oldest ones, Puerta de San Vicente and Puerta del Alcázar.
