The Ross, Skye and Lochaber constituency is one of three Westminster constituencies covering the Highland council area, the other two being Inverness, Nairn, Badenoch and Strathspey and Caithness, Sutherland and Easter Ross. Ross, Skye and Lochaber covers a central portion of the council area, with Inverness, Nairn, Badenoch and Strathspey to its south and east and Caithness, Sutherland and Easter Ross to its north. Ross, Skye and Lochaber includes the Black Isle on the east coast of Scotland and, in the west, the Hebridean island of Skye.
Ward boundaries were redrawn again in 2007, and the management areas were abolished in favour of three new corporate management areas. The new areas consist of groups of the new wards, and boundaries are similar to those of the Westminster constituencies, as created in 2005. Two areas, the Caithness, Sutherland and Easter Ross area and the Ross, Skye and Lochaber area, have the names of Westminster constituencies. The name of the third area, the Inverness, Nairn, and Badenoch and Strathspey area, is very similar to that of the third constituency.
