Sir John Macdonald Kinneir (February 3, 1782 - June 11, 1830) was a Scottish army officer of the East India Company, diplomat and traveller. In 1804 he was appointed ensign in the Madras infantry, and posted in 1807 as lieutenant. He was attached to Sir John Malcolm's mission in Persia between 1808–9, during which time he travelled widely. He produced a Gazeteer of Persia in 1813, which for many years remained the best source of geographical data for that part of the world. In 1824 he was appointed envoy to Fath-Ali Shah Qajar of Persia, for the East India Company, arriving in time for the Russo-Persian War (1826–28).
