Ross and Cromarty (), sometimes referred to as Ross-shire and Cromartyshire, is a variously defined area in the Highlands and Islands of Scotland. There is a registration county and a lieutenancy area in current use, the latter of which is in extent. Historically there has also been a constituency of the Parliament of the United Kingdom (1832 to 1983), a local government county (1890 to 1975), a district of the Highland local government region (1975 to 1996) and a management area of the Highland Council (1996 to 2007). The local government county is now divided between two local government areas: the Highland area and Na h-Eileanan Siar (the Western Isles). Ross and Cromarty border Sutherland to the north and Inverness-shire to the south.
