Kilvaxter (Scottish Gaelic: Cille Bhacastair) is a crofting township on the Trotternish peninsula of the Isle of Skye in the Highlands of Scotland. It is in the council area of Highland. The A855 road passes through the area. Kilvaxter is 5 kilometres (3 miles) north of Uig. A Souterrain exists close to Kilvaxter, and was discovered in April 2000, when a lintel collapsed, and it became visible at the surface. It was excavated and is now open to the public.
