King's Quay is a place on the north east coast of the Isle of Wight, an island off the South Coast of England. It comprises the estuary of a stream called Palmer's Brook, situated between East Cowes and Wootton Creek, about 2 miles (3.2 km) north west of Wootton. It is said, probably apocryphally, to have been the place that King John fled to after signing Magna Carta, from which it derives its name.
