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 21⁄3 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.
