Aonach Beag is a mountain in the Highlands of Scotland in the remote area between Loch Ericht and Loch Laggan located about northwest of Ben Alder. Its prominence is with its parent peak, Geal-Charn, about to the east. In Gaelic, Aonach Beag means little ridge despite it being a Munro. It should not be confused with the better-known Munro near Ben Nevis, also called Aonach Beag, about to the west.
