Loch Kirkaig is a small tidal sea loch, located in the region and parish of Assynt in south-west of Sutherland, in the west coast of Scotland and in the Scottish Highlands.

[2] The name Kirgaig comes from old Norse, Kirkju-vik meaning church bay, perhaps suggesting that in Viking times, there was a church, with a village located in the bay.

[3] Inverkirkaig lies at the head of the sea loch, surrounding a small sand and pebble beach.

The principal settlement in the area is the village of Lochinver in Assynt, which is located 2 km northwest of the beach, along the unnamed coast road.

[4] The small island of Sgeir Mhòr is located close to the southern coast of the bay.
