a seaport-town of Devonshire, at the mouth of the Dart, 31 miles S.W. from Exeter, and 12 miles from Torquay. It stands in the recess of a spacious bay capable of containing 500 sail, and is defended by an ancient castle and a battery. The river, which is crossed at Dartmouth by a floating bridge, is navigable as far as Totness. The town formerly carried on a considerable trade with Newfoundland, but this has been almost entirely alienated. It is now for the most part dependent on the coasting trade, and the trade with the Mediterranean. The principal exports are cider and barley. Dartmouth is one of the quarantine ports of the channel. The town contains several handsome churches, and munificent charitable endowments. Its occupation was strongly contested in the parliamentary war; the town having been besieged by Prince Maurice in 1643, and retaken by Fairfax in 1646. Pop. (1851) 4508.
