Saint-Louis-de-Gonzague (French pronunciation: [sɛ̃ lwi də ɡɔ̃zaɡ]) is a parish municipality in the Beauharnois-Salaberry Regional County Municipality in the Montérégie region of Quebec, Canada.

One of the first settler in the area was Charles Larocque (1784-1849), who was deputy for Vaudreuil in the Legislative Assembly of Lower Canada from 1833 to 1838.

He managed the first general store in the village, that was originally named after him: Rocqueville, or sometimes spelled Rocque-ville or Larocqueville.

Other original settlers came mostly from Saint-Timothée, Les Cèdres, and Île Perrot in the middle of the 19th century.

[1] In 1845, the parish was formed, named after the Italian Jesuit Luigi Gonzaga.
