Sir Francis Cockburn (; 10 November 1780 – 24 August 1868) served in the British Army, played an important role in the early settlement of eastern Canada and was a colonial administrator. Cockburn was born in England in 1780. He was the fifth and last son of Sir James Cockburn, 8th Baronet (1729–1804) and his second wife Augusta Anne Ayscough. His maternal grandfather was Francis Ayscough, Dean of Bristol and royal tutor. Cockburn Town, the largest settlement on San Salvador Island in the Bahamas, was named after him, as was Cockburn Island in Ontario.
