Letterkenny (CDR) railway station served the town of Letterkenny in County Donegal, Ireland.
The station opened on 1 January 1909 when the County Donegal Railways Joint Committee built the Strabane and Letterkenny Railway from Strabane to Letterkenny.
The station was built adjacent to the existing Letterkenny (LLS) railway station operated by the Londonderry and Lough Swilly Railway and had a siding connection to the system of this company.
The station had non-passenger facilities as freight was an important part of the business rationale for the railway's construction. There was a goods store, a crane, cattle pens, signal box, water tank, turntable and an engine shed.
The last train arrived on 31 December 1959. It closed on 1 January 1960. CDRJC road services continued to use the station until they were taken over by CIÃÂ on 10 July 1971. The station building is now used by Bus ÃÂireann as the Letterkenny bus station.
