Brecqhou is one of the Channel Islands and part of the Bailiwick of Guernsey. It is located just west of Sark and has a surface area of approximately 200 acres (0.81 km2). Sark claims it as a tenement, and the Ministry of Justice, the department of the United Kingdom government with responsibility for the Channel Islands, considers Brecqhou part of Sark - but this is disputed by Brecqhou's current tenants.
