Dun Carloway is a broch situated in the district of Carloway, on the west coast of the Isle of Lewis, Scotland. It is a remarkably well preserved broch - on the east side parts of the old wall still reach to 9 metres tall.

Excavation in the northeastern room found at least three peat-ovens used in the period 400-700. In this room were also a lot of pottery remains, as well as a fragment of a quern-stone and a collection of snail shells. The fireplaces contained no animal bones, which makes a domestic (preparing meals) use of the fires seem unlikely. A more industrial application is also unlikely because of the absence of tools that were used in making ironwork. Probably the northeastern room was only used for the manufacture of earthenware pots.
