Loch Bà is a shallow irregular shaped freshwater loch on Rannoch Moor, Argyll and Bute, in the Scottish West Highlands, within the Highland council area of Scotland.

At the southwestern end sits Loch Coulavie located at the base An Tudair Beag and a slightly higher elevation.

Also at the southwestern end, the River Affric flows into the tiny loch of Loch Na Camaig.
