Skye, Lochaber and Badenoch is a county constituency of the Scottish Parliament covering part of the Highland council area. It elects one Member of the Scottish Parliament (MSP) by the first past the post method of election. Under the additional-member electoral system used for elections to the Scottish Parliament, it is also one of eight constituencies in the Highlands and Islands electoral region, which elects seven additional members, in addition to the eight constituency MSPs, to produce a form of proportional representation for the region as a whole.
The seat was created for the 2011 Scottish Parliament election, and replaced most of the former constituency of Ross, Skye and Inverness West and part of the former Inverness East, Nairn & Lochaber constituency. The remaining portions of the two former seats (consisting mostly of the less rural area surrounding and including Inverness) was moved into a new seat called Inverness and Nairn.
The seat has been held by Kate Forbes of the Scottish National Party since the 2016 Scottish Parliament election.
The Skye, Lochaber and Badenoch constituency is one of eight forming the Highlands and Islands electoral region. The other seven constituencies in the region are Argyll and Bute, Caithness, Sutherland and Ross, Inverness and Nairn, Moray, Na h-Eileanan an Iar, Orkney Islands, and Shetland Islands. The region covers most of Argyll and Bute council area, all of the Highland council area, most of the Moray council area, all of the Orkney Islands council area, all of the Shetland Islands council area and all of Na h-Eileanan Siar.
