The River Farrar (Scottish Gaelic: Farar / Uisge Farair) is a river in the Highlands of Scotland. It begins at the confluence of the Uisge Misgeach and the Garbh-uisge, which flows out of Loch Monar. The river flows along Glen Strathfarrar, through Loch a' Mhuillidh and Loch Beannacharan, which is dammed as part of the Affric-Beauly hydro-electric power scheme.
It joins with the River Glass near the village of Struy, from there the combined river is known as the River Beauly.
