Élie-Oscar Bertrand (March 3, 1894 – October 21, 1980) was an Ontario businessman and political figure. He represented Prescott in the Canadian House of Commons as a Liberal member from 1929 to 1949.
He was born in L'Orignal, Ontario in 1894, the son of Louis Bertrand. He married Armande Scott in 1915. He was a merchant at L'Original and served as clerk for the municipal council and was mayor from 1922 to 1929. Bertrand was first elected to the House of Commons in an 1929 by-election held after Louis-Mathias Auger resigned his seat. He held the Prescott seat until he was defeated in 1949 by Raymond Bruneau. Shortly afterwards, Bertrand was named to the Canadian Farm Loan Board, a predecessor to Farm Credit Canada, and served until 1960.
