Inverkeithny is a village in the Formartine area of Aberdeenshire, Scotland. The village lies near where the Burn of Forgue flows into the River Deveron, west of Turriff and south-east of Aberchirder. In 1990, it was described by Charles McKean as "near-deserted".
Netherdale House, an Italianate mansion on a bluff high above the river, was built in 1774, while Muiresk House dates to before 1604. Carnousie, a Z-plan chateau of the Ogilvies of Carnousie, was built in 1577.
Gordon Hay, the author of the first complete translation of the Bible into the Scots language was raised in Inverkeithny.
The parish church was built, probably by Alexander and William Reid, in 1881, costing nearly ã2,000. The church is now owned and operated by Inverkeithny Kirk Preservation Trust, a registered Scottish charity.
