Waberthwaite is a small, former rural civil parish on the south bank of the estuary of the River Esk, in Copeland, Cumbria, England. Since 1934 it has been part of the combined parish of Waberthwaite and Corney, which covers 10 square miles and has a population of 246. It is located opposite Muncaster Castle and the village of Ravenglass which lie on the north bank of the Esk. It is well known for its Cumberland sausages, and lists among its other assets a granite quarry that is a Site of Special Scientific Interest (SSSI); the Esk estuary, which forms part of the Drigg Coast Special Area of Conservation (SAC) - a designation for areas of European importance; the 800-year-old St. John's Church, and the remains of two Anglian/Norse crosses of an earlier period. Archeological finds within 3 kilometres of Waberthwaite indicate that the area has been continuously inhabited since Mesolithic times.
