Carn Aosda is a Munro of 915.3 m in Aberdeenshire. It clears the 3,000 ft line (914.4 m) by only 0.9 m.
All four of its nearest neighbours are higher, up to Glas Maol at 1,067.7 m. Its key col leads to Carn a' Gheoidh, not to its nearest higher summit, The Cairnwell. It is a Munro but not a Marilyn: its 122.1 m of drop is short of 150 m.
