The Devizes branch line was a railway line from Holt Junction, Wiltshire to Patney and Chirton, Wiltshire, and named after Devizes, the largest town on the line. The branch was opened by the Great Western Railway in 1857, and from 1862 when the Reading-Hungerford line reached Devizes it became part of the shortest route from London to the West Country. Those services were re-routed in 1900, and the line closed in 1966.
