Louis Lacoste (April 3, 1798 – November 26, 1878) was a notary and political figure in Lower Canada and then Canada East, Province of Canada (now Quebec). He was a member of the Legislative Assembly of Lower Canada, supporting Louis-Joseph Papineau and the Parti patriote. During the Lower Canada Rebellion he was imprisoned without trial, for his activities in the lead-up to the Rebellion. Following the creation of the Province of Canada, he was a member of the new Legislative Assembly for several years, and then a member of the Legislative Council. He was one of the original members of the Senate of Canada from 1867 to 1878.
