Carnasserie Castle is a 16th-century ruined tower house located around a mile north of the village of Kilmartin, Argyll and Bute, Scotland (Scottish Gaelic: Cille Mhàrtainn, Earra-Ghàidheal agus Bòd, Alba). It was built by Rector of Kilmartin John Carswell (Scottish Gaelic: Seon Carsuail; c. 1522 – 1572). He published the first book to be printed in Scottish Gaelic, a translation of John Knox's Book of Common Order.
After the death of John Carswell the property was acquired by his patron the Earl of Argyll who then then sold it in 1643 to Sir Dugald Campbell, 3rd Baronet of Auchinbreck. It was blown up by government forces when his successor Duncan Campbell participated in the failed 1685 Argyll's Rising and never repaired. The castle comprises a 5-storey tower house, with a longer three storey hall house. It is noted for its finely-carved features. There are good views down to Kilmartin Glen from the parapets of the property. Kilmartin Glen has a high number of Neolithic and Bronze remains and Kilmartin Museum is located in the village. The castle is in the care of Historic Environment Scotland - Àrainneachd Eachdraidheil Alba.
