Ardmeanach (Scottish Gaelic:Ard Meanach) is a peninsula on the Isle of Mull. It is the middle one out of three westward-facing peninsulas on the island, and the name in Gaelic means "Middle Headland" or "Middle Height". It is about 20km (12 miles) long and 6km (4 miles) wide, and lies between Loch Scridain and Loch Na Keal.

It is mountainous and includes Ben More, the highest mountain on the island. It is largely uninhabited, with a few isolated settlements along the coast. It is cut in two by a narrow valley (Gleann Seilisdeir) which runs north–south between the two sea lochs and carries the B8035 road. The peninsula (or its western end) is a Special Area of Conservation.
