The town of Bienfait was incorporated as the Village of Bienfait on April 16, 1912 becoming a town on March 1, 1957. The town was named by the Canadian Pacific Railway after Antoine Charles Bienfait, a banker with Adolphe Boissevain & Company of Amsterdam, due to the firm's involvement in the sale of CP shares in Europe.[3]
In 1931 striking coal miners marched from Bienfait to nearby Estevan, resulting in the Estevan Riot.
