Sanna (Scottish Gaelic: Sanna) is a hamlet at the far western tip of the Scottish peninsula of Ardnamurchan, in Lochaber, Highland. It is one of the most westerly settlements on the mainland of Great Britain, and consists of a small collection of crofts and houses around a series of unspoilt sandy beaches. It is the setting for most of Alasdair Maclean's autobiographical book Night Falls on Ardnamurchan.

Ardnamurchan (/ˌɑːrdnəˈmɜːrxən/, Scottish Gaelic: Àird nam Murchan: headland of the great seas) is a 50-square-mile (130 km2) peninsula in Lochaber, Highland, Scotland, noted for being very unspoilt and undisturbed. Its remoteness is accentuated by the main access route being a single track road for much of its length.
Strictly speaking Ardnamurchan covers only the peninsula beyond the villages of Salen (in the south) and Acharacle (in the north), but nowadays the term is used more generally to include the neighbouring districts of Sunart, Ardgour, Morvern, and even Moidart (which was part of the former county of Inverness-shire, not Argyll).
Ardnamurchan Point, which has a 36-metre (118 ft) tall lighthouse built on it, is commonly described as the most westerly point of the British mainland although Corrachadh Mòr, a kilometre to the south, is a few metres further west.
