Nine Elms Locomotive Works were built in 1839 by the London and South Western Railway (LSWR) adjoining their passenger terminus near the Vauxhall end of Nine Elms Lane, in the district of Nine Elms in the London Borough of Battersea. They were rebuilt in 1841 and remained the principal locomotive carriage and wagon workshops of the railway until closure in stages between 1891 and 1909. Thereafter a large steam motive power depot remained open on the site until 1967, serving Waterloo railway station.

The London and South Western Railway was a railway company in England from 1838 to 1922. Originating as the London and Southampton Railway, its network extended to Dorchester and Weymouth, to Salisbury, Exeter and Plymouth, and to Padstow, Ilfracombe and Bude. It developed a network of routes in Hampshire, Surrey and Berkshire, including Portsmouth and Reading.
