John James Deutsch (1911 - March 18, 1976) was a prominent Canadian economist who served as the first chairman of the Economic Council of Canada and as principal (1968-74) of Queen’s University. Born in Quinton, Saskatchewan, and educated at Queen’s, he worked in journalism and in government as well as the university. In 1947 Prime Minister William Lyon MacKenzie King asked Deutsch to negotiate a trade agreement with the United States that would have produced a sweeping liberalization of Canada-U.S. trade had it not in the end been repudiated by King's government. He subsequently became an economics professor at Queen’s and then the university's vice-principal (administration) before being selected as principal.

Deutsch, who died in 1976, is remembered at Queen’s through the John Deutsch University Centre (JDUC), the student union building, and through the John Deutsch Institute for the Study of Economic Policy in the university's department of economics.

In 1969 he was made a Companion of the Order of Canada.
