The Sheriff of Kincardine, also known as The Mearns, was historically a royal appointment, held at pleasure, which carried the responsibility for enforcing justice in Kincardine, Scotland. 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.
Following a general merger of the sheriffdoms in 1870 the position became the Sheriff of Aberdeen and Kincardine.
