Charles Daoust (January 23, 1825 – February 27, 1868) was a lawyer, journalist and political figure in Canada East.
He was born in Beauharnois, Lower Canada in 1825, the son of a farmer, and studied at the Collège Saint-Pierre at Chambly.
He originally planned to become a priest but later articled in law with Lewis Thomas Drummond at Montreal and was called to the bar in 1847.
Daoust supported Joseph Papin's proposal for a school system not based on religious affiliations, a viewpoint opposed by the clergy in the province.
Daoust was a member of the Institut canadien de Montréal and served as its president in 1860.
