Sunbury railway station serves the town of Sunbury-on-Thames, in the Spelthorne district of Surrey, England.

The station and all trains serving it are operated by South Western Railway.

The Shepperton branch opened to passengers with a single track on 1 November 1864.

Its promoters' scheme first intended to link this to what became today's District line and potentially to Woking railway station.

[1] The curve linking Fulwell and Teddington initially opened to freight on 1 July 1894 and then carried passengers on 1 June 1901 as the replacement principal route.
