Carn an t-Sagairt Mor is a Munro of 1,047 m in Aberdeenshire. Its key col leads to Lochnagar – Cac Carn Beag, not to its nearest higher summit, Carn a' Choire Bhoidheach.
All four of its nearest neighbours lie to the east, so it stands at the western edge of its group. On the Munros height ladder it sits between Chno Dearg (1,047.5 m) and Creag Mhor (Perth and Kinross, Stirling) (1,046.8 m). It is a Munro but not a Marilyn: its 85 m of drop is short of 150 m.
