The Scottish North Eastern Railway was a railway company in Scotland operating a main line from Perth to Aberdeen, with branches to Kirriemuir, Brechin and Montrose. It was created when the Aberdeen Railway amalgamated with the Scottish Midland Junction Railway on 29 July 1856. It did not remain independent for long, for it was itself absorbed by the Caledonian Railway on 10 August 1866.
Much of its network closed in 1967 when the former North British Railway route to Aberdeen via Dundee became the main route.
