The Maryport & Carlisle Railway (M&CR) was an English railway company formed in 1836 which built and operated a small but eventually highly profitable railway to connect Maryport and Carlisle in Cumbria, England. There were many small collieries in the area and efficient access to the harbour at Maryport was important. After 1918 the industries on which the line was dependent declined steeply, and the railway declined accordingly; the branch lines closed, but the original main line remains open and forms part of the Cumbrian Coast Line between Carlisle and Barrow in Furness.
