Cameron Ross McIntosh (July 7, 1871 – August 8, 1971) was a Canadian politician and newspaper publisher.
In 1912, McIntosh acquired the North Battleford News, a Saskatchewan newspaper that had been established several years earlier.
During his fifteen-year tenure in government, McIntosh served as chairman of the Industry and International Relations Standing Committee and towards the end of his parliamentary career was adviser to Canada's delegates to the International Labor Conference in Geneva.
At age 88, McIntosh received a CWNA (Canadian Weekly Newspapers Association) Honorary Life Membership.
He is one of only six members of the Canadian Parliament to reach centenarian status, the others being David Wark (1805–1906), Georges-Casimir Dessaulles (1827–1930), Sir William Mulock (1844–1944), Norman McLeod Paterson (1883–1983) and Charles Willoughby (1894–1995).
