Élie-Oscar Bertrand (March 3, 1894 - October 21, 1980) was a businessman and political figure in Ontario, Canada. Bertrand represented Prescott in the House of Commons of Canada 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'Orignal 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 a 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.|- |Liberal|Élie-Oscar Bertrand|align="right"| 5,152 |Independent Liberal|Gustave Gustave Évanturel|align="right"| 3,562 |}
