Sir Byron Edmund Walker, CVO (14 October 1848 – 27 March 1924) was a Canadian banker. He was the president of the Canadian Bank of Commerce from 1907 to 1924, and a generous patron of the arts, helping to found and nurture many of Canada's cultural and educational institutions, including the University of Toronto, National Gallery of Canada, the Champlain Society, Appleby College, Art Gallery of Ontario and Royal Ontario Museum. In 1910, King George V knighted Walker for his contributions to business and the arts.
