The Ouzel Galley was an Irish merchant ship that set sail from Dublin in the late seventeenth century and was presumed lost with all hands when she failed to return within the next three years. After a further two years had elapsed, however, she mysteriously reappeared with her full complement of crew and a valuable cargo of spices, exotic goods and, it is said, piratical spoils. The ship has entered Irish folklore, and her unexplained disappearance and unexpected reappearance are still the subject of a number of conspiracy theories.
