An Coileachan is a Munro of 924 m in Highland. Its key col leads to Sgurr Mor, not to its nearest higher summit, Meall Gorm.
All four of its nearest neighbours lie to the north, so it stands at the southern edge of its group. It shares its height of 924 m with Sgurr nan Each and Elidir Fawr. On the Munros height ladder it sits between Sgurr nan Each (924 m) and Beinn Alligin – Tom na Gruagaich (921.8 m). It is a Munro but not a Marilyn: its 148.3 m of drop is short of 150 m.
