Mount Keen (Scottish Gaelic: Monadh Caoin) is a 939-metre-high (3,081 ft) mountain in Scotland and the most easterly Munro.

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.

There is a wide forestry track most of the way to the foot of the mountain if approaching from Aboyne and Glen Tanar.

The path quality on the mountain itself is also good on this route although it becomes quite rocky near the top and can be frozen and slippery in winter months.

Mobile phone reception is excellent from the summit for Vodafone and O2 users and possibly many others as there is a direct line of sight with the Durris mast.
