Uist, Northyōˈĭst, ōˈ–, and South Uist, islands, two of the Outer Hebrides, Western Isles council area, NW Scotland. North Uist (1985 est. pop. 3,300), is 18 mi (29 km) long and 13 mi (21 km) wide, with a much indented coast (Lochs Maddy, Eport, and others). The east is hilly and boggy, but the west has some fertile land. Lochmaddy is the chief town. Most of the inhabitants are crofters. South Uist (1985 est. pop. 4,600) is c.22 mi (35 km) long and 7 mi (11 km) wide, with Lochs Boisdale, Eynort, and Skiport indenting the east coast. A testing range for rockets was erected there in 1954. Lochboisdale is the leading town, and the village of Milton was the birthplace of the Jacobite heroine Flora Macdonald. North Uist and South Uist are separated from each other by Benbecula and several smaller islands; the main islands and two smaller ones are linked by bridges and causeways.
