Barrow-In-Furness, a municipal borough, manufacturing town, and seaport of Lancashire, England, on the S. W. shore of the peninsula of Lower Furness, opposite Walney island, the terminus of the Furness railway, 4 m. S. W. of Dalton, and 50 m. N. N. W. of Liverpool; pop. in 1871, 17,992 (in 1847, only 300). The rapid progress of the town is due to its iron and steel works. The annual export of iron ore is estimated at 600,000 tons, and of copper ore at 3,000 tons. The steel works convert about 1,000 tons of pig iron weekly into Bessemer steel, the Barrow hematite iron and steel company being one of the largest establishments of the kind in the world. Great quantities of coal are imported from Wales, and of timber from Canada and the Baltic. The town received a charter of incorporation in 1867, and the duke of Devonshire, the chief owner of the land, inaugurated the new docks in the same year. They are unrivalled in Lancashire in extent and position, except by those of Birkenhead. The town contains a line town hall and other public buildings.

Bathing establishments, and a monument of Mr. Noble, the chief promoter of railway and manufacturing enterprise, were inaugurated in 1872.
