Cashelnagore railway station served the village of Cashelnagore in County Donegal, Ireland.
The station opened on 9 March 1903 when the Londonderry and Lough Swilly Railway opened their Letterkenny and Burtonport Extension Railway, from Letterkenny to Burtonport. It closed on 3 June 1940 when the LLSR closed the line from Tooban Junction to Burtonport in an effort to save money. It was used in the 1992 film The Railway Station Man.
