In English folklore, Black Shuck, Old Shuck, Old Shock or simply Shuck is the name given to an East Anglian ghostly black dog which is said to roam the coastline and countryside of East Anglia, one of many ghostly black dogs recorded in folklore across the British Isles. Accounts of Black Shuck form part of the folklore of Norfolk, Suffolk, the Cambridgeshire fens and Essex, and descriptions of the creature's appearance and nature vary considerably; it is sometimes recorded as an omen of death, but, in other instances, is described as companionable.
