Gribshunden or Griffen (English: "Griffin-Hound" or "Griffin"), also known by several variant names including Gribshund, Gripshunden, Gripshund, Griff, and Griffone, was a Danish warship, the flagship of John, King of Denmark (r. 1481–1513). Gribshunden sank in 1495 after catching fire while in the Baltic Sea off the coast of Ronneby in southeastern Sweden; she is one of the best-preserved wrecks from the late medieval period.
