Lanarkshire, Or Clydesdale, an inland county of Scotland, bordering on the counties of Dumbarton, Stirling, Linlithgow, Edinburgh, Peebles, Dumfries, Ayr, and Renfrew; area, 888 sq. m.; pop. in 1871, 769,339. The river Clyde traverses the county from S. S. E. to N. N. W., and with its tributaries is noted for beautiful river scenery. The falls of Bonning-ton, Corra Linn, and Stonebyres are much visited by lovers of the picturesque. The county is nominally divided into three wards, the upper or south ward, the middle, and the lower or north ward, the last containing the city of Glasgow; the upper is mountainous, the middle hilly, and the lower level. The Lowther hills, along the south, are from 2,000 to 3,000 ft. high, but afford extensive ranges of pasturage. In these hills are valuable lead mines, consisting of four principal veins 4 to 10 ft. thick, one of which has been wrought to a depth of 140 fathoms, the pure ore in one place having been found 14 ft. wide. Coal is however the most important of the mineral treasures of the county, the fields comprising 55,000 acres. There are also important iron mines and immense fields of fire clay. Dairy husbandry is carried on with great success. Oats are the principal grain crop, but wheat and barley are extensively grown.

Clydesdale is noted for its orchards, as well as for its breed of draught horses. It is the seat of vast manufacturing industry in collieries, iron works, and cotton, flax, silk, and woollen. In the time of James III. of Scotland gold was found in Lanarkshire, from which coins were struck called unicorns. Capital, Lanark.
