Barrow-in-Furness is a town and borough in Cumbria, North-West England. Historically part of Lancashire, it was incorporated as a municipal borough in 1867 and merged with Dalton-in-Furness Urban District in 1974 to form the Borough of Barrow-in-Furness.

Barrow's population is 67,600, making it the second largest urban area in Cumbria after Carlisle, although it is geographically closer to the whole of Lancashire and most of Merseyside.

Barrow in Furness is famous for being a large industrial town which grew from a tiny 19th Century hamlet to the biggest iron and steel centre in the world, and a major ship-building force, in just 40 years.
