Fordoun (Pronounced "For-Dun") is a parish and village in Aberdeenshire, Scotland. Fothirdun (possibly "the lower place"), as it was historically known, was an important area in the Howe of the Mearns. Fordoun and Auchenblae, together with their immediate districts form the Parish of Fordoun with the Parish Church in the vicinity of the original settlement, now absorbed by Auchenblae.
In the 19th Century a railway station was opened approximately 3 miles to the South East of Fordoun Church and the original settlement. A village grew at the site of the railway named Fordoun Station (opened in November 1849 and closed in June 1956) where there were also a number of shops, but only a pub and a seasonal farm shop remain. In the time since the founding of the railway station the village formerly known as Fordoun Station has come to be known simply as Fordoun and the site of original settlement has been absorbed by Auchenblae.
