Andrew Graham Ballenden Bannatyne (October 31, 1829 – May 18, 1889) was a Canadian politician, fur trader and leading citizen of Winnipeg, Manitoba.

Bannatyne was born on the island of South Ronaldsay, Orkney, in Scotland and was three years old when his father, a British government fisheries official in Stromness, died.

[2] From 1846, Bannatyne was stationed at Norway House, Rupert's Land, in what is now Manitoba as a junior clerk at the trading post.

In the 1874 federal election, he was defeated in his bid for a federal parliamentary seat in Selkirk, being narrowly defeated by Hudson's Bay Company official Donald A. Smith,[2] but was elected in 1875 to the House of Commons of Canada as the Liberal MP for Provencher, filling a vacancy caused by the expulsion of Riel from the House of Commons and his banishment from Canada.

[1] His heavy indebtedness worsened his already poor health, and he began to winter in the southern United States in order to ease his constitution.
