Captain John Hatley, RN (c. 1762 – 12 December 1832) was an officer of the British Royal Navy during the late eighteenth and early nineteenth centuries. Hatley is most noted for being one of the junior officers on board Captain James Cook's third voyage in HMS Resolution, aged approximately 14. He later went on to serve in the French Revolutionary and Napoleonic Wars, receiving promotion after helping to thwart a mutiny in 1797 and later commanding frigates in several campaigns.
