Stewart Wallace (23 June 1884 – 11 March 1970) was a Canadian historian, librarian, and editor.
His historical reference works were considered 'of inestimable value in Canadian studies'.Canadian professor of political economy Harold Innis (1894 – 1952) was influenced by a maxim of the then McMaster University professor Wallace, 'that the economic interpretation of history is not the only interpretation but is the deepest interpretation'.
