The Leek and Manifold Valley Light Railway (L&MVLR) was a narrow gauge railway in Staffordshire, Great Britain that operated between 1904 and 1934. When in operation, the line mainly carried milk from dairies in the region, acting as a feeder into the standard gauge system. It also served small villages and beauty spots. The line was built to a gauge of 2' 6" and to light rail standards to reduce construction costs, and came about largely as a consequence of the Light Railways Act 1896 which allowed private companies to construct short railways to serve more remote places which the standard gauge systems would not have reached.
