a royal parliamentary and municipal borough and seaport of Scotland, county of Fife, on the N. shore of the Firth of Forth, 10 miles W.N.W. from Edinburgh. It is beautifully situated on the brow of an acclivity rising from the margin of a bay called St Margaret's Hope. The oldest existing charter of the town is one from William the Lion, confirming one of unknown date. This charter was confirmed by James VI. in 1598. The widowed queen of Robert III., the beautiful Arabella Drummond, resided here. Before the convention of royal boroughs was appointed to be held in Edinburgh, Inverkeithing was the place of its meeting. No manufactures are carried on in the town, but in the vicinity are a distillery, brewery, brickwork, tanwork, shipbuilding yard, and two foundries. The harbour is accessible to vessels of 200 tons at spring tide. The chief export is coal, which abounds in Inverlochy the vicinity. Inverkeithing is a contributory borough to Stirling in returning a member to parliament. Pop. (1851) Inverness, of municipal borough, 1497; of parliamentary borough, 1852.
