Lochaber (/lɒxˈɑːbər/ lokh-AH-bər; Scottish Gaelic: Loch Abar) is a name applied to a part of the Scottish Highlands. Historically, it was a provincial lordship consisting of the parishes of Kilmallie and Kilmonivaig. Lochaber once extended from the Northern shore of Loch Leven, a district called Nether Lochaber, to beyond Spean Bridge and Roybridge, which area is known as Brae Lochaber or Braigh Loch Abar in Gaelic. For local government purposes, the name was used for one of the landward districts of Inverness-shire from 1930 to 1975, and then for one of the districts of the Highland region from 1975 to 1996. Since 1996 the Highland Council has had a Lochaber area committee.
The main town of Lochaber is Fort William. Other moderate sized settlements in Lochaber include Mallaig, Ballachulish and Glencoe.
