Coy Burn is a stream that rises in the hills north of Banchory in Aberdeenshire, Scotland. Coy Burn discharges to the River Dee at Milton of Crathes. The Coy Burn along with certain other natural waters of Scotland has been under study for its role in Salmon spawning. A number of prehistorical features lie nearby including Balbridie and Bucharn to the south of the River Dee.
