Mount Keen () is a 939 m (3,081 feet) high mountain in Scotland and the most easterly Munro. It can be accessed from several directions, South from Glen Mark, North from Glen Tanar, and East to Braid Cairn. It is a moderate walk which is most popularly started by mountain bike, riding through the native Caledonian pine forest of Glen Tanar from Aboyne. On a good day, the Cairngorms, especially Lochnagar, can be seen. The summit is marked by a trig point.
