Downshire railway station serves eastern Carrickfergus in County Antrim, Northern Ireland.

This station opened on 1 April 1925 and was known for most of its early life as Downshire Park. Northern Ireland Railways renamed the halt in the late 1970s. The station's signposts prior to the 2008 refurbishment named the station as "Downshire Halt", a name by which the station is still locally known.

The Belfast-bound platform was extended during summer 2011 to allow longer trains to operate. The Larne-bound platform was similarly refurbished in early 2012.

On weekdays, there is a half-hourly service to Belfast Grand Central. In the other direction, there is a half-hourly service with the terminus alternating between Whitehead and Larne Harbour every half an hour. At peak times some trains terminate at Larne Town.

On Saturdays, the service remains half-hourly with the same alternating pattern, and there are less peak services.

On Sundays, the service reduces to an hourly operation in both directions.
