Chard Junction railway station was situated on the London and South Western Railway’s West of England Main Line about 1 mile (1.6 km) southeast of the village of Tatworth in Somerset, England. It was the junction of a short branch line to Chard. It was opened in 1860 as Chard Road, and closed in 1966. An adjacent milk depot was served by its own sidings from 1937 to 1980. Chard Junction signal box remained open to control Station Road level crossing and a passing loop on the long section of single track railway between Yeovil Junction and Pinhoe until March 2021, when control was passed to Basingstoke.

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.
