John Askin Jr. (c1765–1820) was a fur trader, merchant, and official in Upper Canada and Michigan. He and his wife, Madelaine, are remembered as being instrumental in the invention of the Mackinaw jacket in 1811. To Askin's disappointment, the British home country did not follow up on this victory. Its government signed a treaty in 1814 to restore the pre-1812 border. John Askin Jr. died in British Canada on January 1, 1820. His son, John Baptist Askin, born in 1788, became a prominent resident and community leader in London, Ontario.
