The Flying Dutchman is a legendary ghost ship, allegedly never able to make port, but doomed to sail the sea forever. The myths and ghost stories are likely to have originated from the 17th-century Golden Age of the Dutch East India Company (VOC) and of Dutch maritime power. The oldest known extant version of the legend dates from the late 18th century. According to the legend, if hailed by another ship, the crew of the Flying Dutchman might try to send messages to land, or to people long dead. Reported sightings in the 19th and 20th centuries claimed that the ship glowed with a ghostly light. In ocean lore, the sight of this phantom ship functions as a portent of doom. It was commonly believed that the Flying Dutchman was a seventeenth-century cargo vessel known as a fluyt.

A ghost ship, also known as a phantom ship, is a vessel with no living crew aboard; it may be a fictional ghostly vessel, such as the Flying Dutchman, or a physical derelict found adrift with its crew missing or dead, like the Mary Celeste. The term is sometimes used for ships that have been decommissioned but not yet scrapped, as well as drifting boats that have been found after breaking loose of their ropes and being carried away by the wind or the waves.
