The Callanish VIII stone setting is one of many megalithic structures around the better-known (and larger) Calanais I on the west coast of the Isle of Lewis, in the Outer Hebrides (Western Isles), Scotland. It is also known locally as Tursachan.{{Canmore |num=4112 |desc=Great Bernera, 'tursachan', Barraglom |access-date=11 September 2024}}

This is a very unusual (and possibly unique) setting, with a semicircle of four large stones on the edge of a cliff on the south of the island of Great Bernera and looking across a narrow strait to Lewis. There is no evidence that the cliff has collapsed here and destroyed half of a complete circle – it would appear that a semicircle was the original intention. The tallest stone is nearly three metres high and the cliff-edge axis of the circle gives a diameter of about 20 metres.
