Auchencastle railway station was a private station which served Auchencastle, near Beattock, in the Scottish county of Dumfries and Galloway. It was used by railwaymen and families and was served by local trains on what is now known as the West Coast Main Line. The nearest station for Auchencastle is now at Lockerbie.

Opened by the Caledonian Railway, it became part of the London Midland and Scottish Railway during the Grouping of 1923 and was then closed by that company.
