Cromartyshire is a traditional county in the north of Scotland, consisting of a series of enclaves within Ross-shire. For administrative purposes Ross-shire and Cromartyshire were organised as a single administrative county of Ross and Cromarty in 1889, which was itself replaced by the Highland region in 1974. The only burgh in the county is the county town, Cromarty.

The nucleus of the county consists of the lands of Cromarty in the north of the peninsula of the Black Isle. To this have joined from time to time various estates scattered throughout Ross-shire, most notably the districts around Ullapool and Little Loch Broom on the Atlantic coast, the area in which Ben Wyvis is situated, and a tract to the north of Loch Fannich - which was acquired by the ancestors of Sir George Mackenzie (1630 - 1714), afterwards Viscount Tarbat (1685) and 1st Earl of Cromarty (1703). Desirous of combining these sporadic properties into one shire, Viscount Tarbat contrived to procure their annexation to his sheriffdom of Cromarty in 1685 and 1698, and the area of the enlarged county now amounts to nearly 370 square miles (958 km²).
