Castle Cluggy is a ruined 15th century castle located on the north side of Loch Monzievaird, Perth and Kinross, Scotland.

The castle replaced an earlier structure.

The Comyn family held the lands in the 14th century.

The castle was in ruins by the middle of the 18th century, after the Murrays commenced construction of Ochtertyre House to the north.
