Seaton Junction is a closed railway station on the West of England Main Line from London Waterloo to Exeter.

Originally named "Colyton for Seaton" the station opened on 19 July 1860 on completion of the Exeter Extension of the London and South Western Railway from Yeovil Junction to Exeter Queen Street.

Originally, trains arriving from the Seaton branch had to reverse into the "down" (westbound) platform.

The location of the station created a major problem for westbound trains stopping at Seaton Junction since it was situated at the start of a six-mile climb at 1 in 80 to the summit of the line at Honiton tunnel.

The steady decline in holiday traffic resulting from increased car ownership in the 1960s led to a gradual run down of services and the branch line and junction station were closed on 7 March 1966 by the Western Region of British Railways.
