The Jade Bight is a bight or bay on the North Sea coast of Germany. It was formerly known simply as Jade or Jahde. Because of the very low input of freshwater, it is classified as a bay rather than an estuary.

The North Sea lies between Great Britain, Denmark, Norway, Germany, the Netherlands, Belgium and France. An epeiric sea on the European continental shelf, it connects to the Atlantic Ocean through the English Channel in the south and the Norwegian Sea in the north. It is more than 970 kilometres (600 mi) long and 580 kilometres (360 mi) wide, covering 570,000 square kilometres (220,000 sq mi).
