Muchalls Castle stands overlooking the North Sea in the countryside of Kincardine and Mearns, Aberdeenshire, Scotland. The lower course is a well-preserved Romanesque, double-groined 13th-century tower house structure, built by the Frasers of Muchalls. Upon this structure, the 17th-century castle was begun by Alexander Burnett of Leys and completed by his son, Sir Thomas Burnett, 1st Baronet, in 1627. The Burnetts of Leys built the remaining four-storey present-day castle.

The House of Burnett is a Lowland and Border Scottish family composed of several branches. The Chief of the Name and Arms of Burnett is James Comyn Amherst Burnett of Leys.
