DON, a river in the south of Aberdeenshire, Scotland, rising in peat-moss to the east of Glen Avon on the borders of Banffshire, at a height of nearly 2000 ft. above the sea. It follows a generally easterly course, roughly parallel with that of the Dee, and a few miles to the south of it, falling into the North Sea close to Old Aberdeen, after a run of 82 m. At the mouth the two rivers are only 21 m. apart. Like its greater neighbour, the Don is an excellent salmon stream. On the left its chief affluents are the Ernan, Nochty, Bucket and Urie; on the right, the Conrie, Carvie, Deskry and Strow. The principal places of interest on its banks are Strathdon, Towie, Kildrummy, Alford, Keig, Monymusk, Inverurie, Kintore and Dyce.
