Costaérès Castle (French: Château de Costaérès, Breton: Kastell Kostaerez) is a neo-Gothic manor house built in the 1890s. It was commissioned by the Lithuanian-Polish mathematician, electrical engineer, and inventor Bruno Abdank-Abakanowicz on a previously uninhabited island of the same name. Because of its magnificent architectural design, it is also referred to as a castle (French: château). The island with the castle is located in the Côtes-d'Armor department in Brittany, France, off the Côte de Granit Rose. Administratively, the manor house belongs to the municipality of Ploumanac'h, but is still located within the municipality of Trégastel. In 1988, the German comedian and actor Dieter Hallervorden purchased the property and had it converted into a second home.
