Costaérès Castle (French: Château de Costaérès, Breton: Kastell Kostaerez) is a neo-Gothic manor house built in the 1890s.

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.

Other notable structures include Château Demeure de Rosmapamon, a historical manor house now functioning as a guesthouse, and Castel Beau Site, a grand hotel nearing its 100th anniversary, both offering unique insights into the region's architectural past.
