The Sheriff of Caithness was historically the royal official responsible for enforcing law and order in Caithness, Scotland.
The sheriffdom of Caithness appears to have been created in the mid 12th century and to have been dissolved and incorporated into the sheriffdom of Inverness in the 13th century. in 1455, William Sinclair, Earl of Caithness gained a grant of the justiciary and sheriffdom of the area from the Sheriff of Inverness. Prior to 1748 most sheriffdoms were held on a hereditary basis. From that date, following the Jacobite uprising of 1745, the hereditary sheriffs were replaced by salaried sheriff-deputes, qualified advocates who were members of the Scottish Bar.
In 1747, the office became known as the Sheriff of Caithness & Sutherland, however the sheriffdoms were disunited in 1806 again being known as the Sheriff of Caithness. It became the Sheriff of Sutherland & Caithness in 1857.[1] In 1870 the office became known as the Sheriff of Caithness, Orkney & Shetland.[2] It was again reorganised as the Sheriff of Caithness, Sutherland, Orkney & Zetland in 1946, but was abolished in 1975 when the current sheriffdom of Grampian, Highland and Islands was created.
