Dundas Harbour (Inuktitut: Talluruti, "a woman's chin with tattoos on it") (74°31′N 82°23′W / 74.517°N 82.383°WCoordinates: 74°31′N 82°23′W / 74.517°N 82.383°W) is an abandoned settlement in Qikiqtaaluk, Nunavut, Canada. It is located on Devon Island at the eastern shore of the waterway also named Dundas Harbour. Baffin Bay's Croker Bay is immediately to the west.
An outpost was established at the harbour in August 1924 as part of a government presence intended to curb foreign whaling and other activity. Hudson's Bay Company leased the outpost in 1933. The following year, 52 Inuit were relocated from Cape Dorset to Dundas Harbour but they returned to the mainland 13 years later.
