Elphin (, which possibly derives from a combination of Norse and Gaelic fjell, "cliff" or "rock", and fionn, "bright") is a crofting township in Assynt, in the Sutherland area of Highland in Scotland. It lies about 15 mi north of Ullapool. The village contains a telephone box, a post box, a tearoom, a Scottish Mountaineering Club Hut, Grampian Speleological Group Hut, a small caravan site and many self-catering options. Assynt Primary School closed in 2001, and the building is now a community hall operated by Elphin Ledmore and Knockan Community Association Limited. The township now has its own website, see external links. Knockan Crag is about 2 mi south of Elphin and Loch Veyatie is about 1/2 mi northwest.
