a seaport and market town of England, county of Cumberland, on the left bank of the Derwent, here crossed by a stone bridge of three arches, about a mile from its mouth, and 7 miles N. by E. of Whitehaven. The lower part of the town is old, with narrow and inconvenient streets, but the upper portion is better built, and contains a number of good houses and a square in which the corn market is held. It has a parish church, rebuilt in 1760; a chapel of ease, erected in 1825 in the Tuscan style; chapels for Independents, Methodists, Presbyterians, and Roman Catholics; several schools, mechanics' institute, subscription library and news-room, theatre, assembly rooms, and a dispensary. Shipbuilding, rope and sail making, &c., are carried on, but the town is chiefly indebted for its prosperity to the extensive coal and iron works in the vicinity, which furnish its principal articles of trade. The harbour is protected by a breakwater, and has extensive quays and commodious warehouses. On 31st December 1858, 97 vessels, of in all 20,363 tons, were registered as belonging to the port; and during that year Workington had 102 vessels having 6616 tons entered, and 1202 vessels having 100,004 tons left the harbour with cargoes. An active salmon-fishery is carried on on the river. Pop. (1851) 5837.
