Callanish (Scottish Gaelic: Calanais) is a village (township) on the West Side of the Isle of Lewis, in the Outer Hebrides (Western Isles), Scotland. A linear settlement with a jetty, it is situated on a headland jutting into Loch Roag, a sea loch. It lies 13 miles west of Stornoway.
Calanais is the location of the Callanish Stones, a cross-shaped setting of standing stones erected around 3000 BC, one of the most spectacular megalithic monuments in Scotland. There is a modern visitor centre which provides information about the main circle and several other lesser monuments nearby.
