Dunyvaig Castle is a ruined medieval stronghold on the Isle of Islay in western Scotland, historically associated with Clan Donald. It occupies a coastal position and is one of the principal castle ruins on Islay.

The site comprises stone remains of curtain walls and domestic buildings clustered around a fortified position on the shoreline, giving views across nearby sea channels. It is visited for its coastal setting and historical associations rather than extensive visitor facilities.

The castle served as a seat of the MacDonalds (Clan Donald) from the medieval period and was involved in conflicts with the Scottish crown in the 16th and 17th centuries. It fell out of use and into ruin thereafter.

The ruin sits on the Isle of Islay off Scotland’s west coast, in Argyll and Bute. The nearest settlements on Islay provide access by road and ferry connections link the island to the Scottish mainland.
