The Sheriff of Ross, Cromarty and Sutherland was historically responsible for enforcing law and order in Ross-shire, Cromartyshire and Sutherland in Scotland.
The area was part of the shire of Inverness from the 12th century.
A Sheriff of Cromarty existed from the mid-13th century, initially with a relatively small jurisdiction around the town of Cromarty, subsequently enlarged in the late 17th century to include various other tracts of land scattered across the province of Ross.
There are a couple of references to a Sheriff of Ross in the 15th century, but the position was not permanently established until 1662, after an act of parliament of 1661 separated Ross-shire from Inverness-shire.
[1] Following a further reorganisation in 1946 it became the Sheriff of Inverness, Moray, Nairn & Ross & Cromarty.
