Knowlton Nash (born November 18, 1927 in Toronto, Ontario) was the former and long-serving senior anchor of the Canadian Broadcasting Corporation's flagship news program, The National. During his tenure, the program was repeatedly reshaped, going from "The National News" to its current iteration. It has often been speculated that Nash was forced to retire from his duties at "The National" as a result of a job offer from American network CBS to his heir apparent, Peter Mansbridge. As a result, Nash was supposedly forced to retire as the CBC did not want to lose its star young reporter - Mansbridge. Nash left his position as CBC news' senior anchor and chief correspondent in 1988, yet remains active in Canadian journalism circles.
Since his retirement he has written a number of books, including a history of the CBC.
