Étienne Mayrand (September 3, 1776 – January 22, 1872) was a Quebec businessman and political figure.
He was born in Montreal in 1776 and went on to work in the fur trade with the North West Company.
He established a business in grain and hay at Rivière-du-Loup (later Louiseville in Maskinongé County), also expanding into real estate and money lending.
Mayrand served in the militia as an officer during the War of 1812, becoming captain and, in 1846, major.
His grandson, Hormidas Mayrand, later served in the Canadian House of Commons.
