The Sea of Ice is an oil painting of 1823–1824 by the German Romantic artist Caspar David Friedrich.
The landscape depicts a shipwreck in the middle of a broken ice-sheet, whose shards have piled up after the impact. The ice has become like a monolithic tomb, or dolmen, whose edges jut into the sky.
The stern of the wreck is just visible on the right. As an inscription on it confirms, this is HMS Griper, one of two ships that took part in William Edward Parry's 1819–1820 and 1824 expeditions to the North Pole.
