History
Settlement began in the early 19th century. In 1831, its first mill was built. In 1852, residents of the Saint-Clément and Saint-Louis parishes petitioned the Archbishop of Montreal for the creation of a new parish, which was granted after land was offered in the new settlement for a church. It construction began in 1863 and completed a year later.

Its post office opened in 1865, and 2 years later, on January 1, 1867, the municipality was established out of territory from Saint-Clément (since 1957 part of Beauharnois) and Saint-Louis-de-Gonzague. It was named after Saint Stephen and Beauharnois County in which it is located. On October 26, 1869, it changed statutes and became the Parish Municipality of Saint-Etienne. This reverted back to Municipality of Saint-Étienne-de-Beauharnois on March 15, 1969.
