Saul Bonnell (December 29, 1871 – March 21, 1973) was a Canadian politician and physician. Bonnell's early life and career was spent in the Canadian Maritimes before he joined the Canadian Pacific Railway and was sent to British Columbia, where he established and worked in several local hospitals. He was mayor of Fernie, British Columbia in 1907, but put his political career on hold to serve with the Canadian Army Medical Corps during World War I. Returning from overseas in 1917, he was elected to the House of Commons of Canada in that year's federal election as the representative of the newly created Kootenay East riding and served until his defeat in 1921. Following this he returned to practicing medicine until his retirement and died at the age of 101 in March 1973.
