Donald Gunn (September 1797 – 30 November 1878) was a Scottish-Canadian businessman, judge, astronomer and politician. He was a member of the Manitoba Provincial Legislative Council (which he helped to abolish).
Gunn was born in Orkney, Scotland, in 1797. He worked in the Canadian North West for the Hudson's Bay Company between 1813 and 1823, and was subsequently a Judge on the Court of Petty Sessions in Red River. He also wrote for the Smithsonian Institution and the Institute of Rupert's Land, and was a member of the Board of Management for Manitoba College (a Presbyterian institution).
Gunn was one of the earliest contributors to the Smithsonian Institution in the field of astronomy.
Gunn was a supporter of Canadian Confederation and the Government of Adams George Archibald. In Manitoba's first general election (27 December 1870), he ran against Provincial Secretary and fellow Archibald-supporter Alfred Boyd. He was defeated by 58 votes to 28.
