Kincardineshire or the County of Kincardine, also known as the Mearns (from the Scottish Gaelic A' Mhaoirne meaning "the stewartry"), is a historic county, registration county and lieutenancy area on the coast of north-east Scotland. It is bounded by Aberdeenshire on the north, and by Angus on the south-west.
The county was named after its original county town of Kincardine, near Fettercairn. The county town was moved to Stonehaven in 1600, by which time the town of Kincardine was in decline; it was subsequently abandoned. Other towns in the county include Banchory, Inverbervie and Laurencekirk.
