Robert Broughton Bryce, PC CC FRSC, (February 27, 1910 – July 30, 1997) was a Canadian civil servant.

In the fall of 1935, he left Britain for Harvard University where, as a graduate student, he introduced Keynesian economics in the United States, with the help of fellow Canadian Lorie Tarshis.

According to John Kenneth Galbraith, Joseph Schumpeter "called Keynes Allah and Bryce his Prophet".

[2] He is the author of Maturing in Hard Times: Canada's Department of Finance Through the Great Depression (McGill-Queen's Press, 1986, ISBN 0-7735-0555-5).

Leading a group of long-serving bureaucrats who gave Canadian government a sense of stability and consistency, Bryce served as secretary to the cabinet and clerk of the Privy Council under Liberal Louis Saint-Laurent and Conservative John Diefenbaker for nine years (1954–1963).
