Wester Ross is an area of the Northwest Highlands of Scotland in the council area of Highland. The area is loosely defined, and has never been used as a formal administrative region in its own right, but is generally regarded as lying to the west of the main watershed of Ross, thus forming the western half of the county of Ross and Cromarty. The southwesternmost part of Ross and Cromarty, Lochalsh, is not considered part of Wester Ross by the local tourist organisation, Visit Wester Ross, but is included within the definition used for the Wester Ross Biosphere Reserve.

Scottish Gaelic, also known as Scots Gaelic or simply Gaelic, is a Goidelic language native to the Gaels of Scotland. As a Goidelic language, Scottish Gaelic, as well as both Irish and Manx, developed out of Old Irish. It became a distinct spoken language sometime in the 13th century in the Middle Irish period, although a common literary language was shared by the Gaels of both Ireland and Scotland until well into the 17th century. Most of modern Scotland was once Gaelic-speaking, as evidenced especially by Gaelic-language place names.
