The Intercolonial Railway of Canada, also referred to as the Intercolonial Railway (ICR), was a historic Canadian railway that operated from 1872 to 1918, when it became part of Canadian National Railways. As the railway was also completely owned and controlled by the Government of Canada, the Intercolonial was also one of Canada's first Crown corporations.

Crown corporations in Canada are government organizations with a mixture of commercial and public-policy objectives. They are directly and wholly owned by the Crown.
