James J. (J.J.) Morrison (1861–1936) was a Canadian farm leader in Ontario, Canada, a founder of the United Farmers of Ontario (UFO) in 1914, and a leader of the co-operative movement. He was the UFO's sometimes controversial general secretary, who was given to making bizarre pronouncements, during the period in which it became a political party and took power in the province following the 1919 provincial election.
