Whitby is a seaside town, port and civil parish in the Scarborough borough of North Yorkshire, England. Situated on the east coast of Yorkshire at the mouth of the River Esk, Whitby has a combined maritime, mineral and tourist heritage, and is home to the ruins of Whitby Abbey where Caedmon, the earliest English poet, lived. The fishing port emerged during the Middle Ages and developed important herring and whaling fleets, and was where Captain Cook learned seamanship.
