Aldie Castle is an historic building east of Crook of Devon, Perth and Kinross, Scotland.

It is a Category A listed building.

This three storey tower house dates to the early 16th century.

[1][2] A two-storey extension was made and a separate parallel three storey range was built and a link range between.

[3] The castle was the former seat of the Mercers, who acquired it from the Murrays of Tullibardine around 1350.
