John O'Connell Bligh (3 March 1834 – 12 October 1880) was a Native Police officer in the British colonies of New South Wales and Queensland. He achieved the rank of Commandant of this colonial paramilitary force from 1861 to 1864. Bligh is probably best known for an incident in Maryborough, where he shot a number of Aboriginal Australians along the main street and into the adjoining Mary River. After retiring from the Native Police, Bligh became a police magistrate in the towns of Gayndah and Gympie.
