Ardnadam (Scottish Gaelic: Àird nan Damh) is a village on the Holy Loch on the Cowal Peninsula, in Argyll and Bute, west of Scotland.

It is located northwest of Hunters Quay and east of Sandbank, and sits across the loch from Kilmun.

[4] Ardnadam Heritage Trail is 2.75 miles (4.43 km) long and climbs to Dunan Hill (Camel's Hump), which has views across Loch Loskin, Dunoon, Holy Loch and the Firth of Clyde.

[5] Other walking trails go beside Loch Loskin, and to the site of an ancient cromlech on the nearby Ardnadam Farm.

[3][6] Lazaretto Point in Ardnadam was the site of a quarantine station, built in 1807, to treat disease brought into the Clyde ports with imported cotton shipments.
