the parish municipality of Saint-Jacques () is a former parish municipality now part of the current regular municipality of Saint-Jacques, Quebec, Canada.
Prior to February 4, 1998, the parish of Saint-Jacques was an independent municipality; on that date, it and the village of Saint-Jacques were merged into the new municipality of Saint-Jacques.
The parish was founded in 1855 on a territory that was commonly known as Saint-Jacques-de-Saint-Sulpice. In 1912, the more urban sector split to became the village municipality of Saint-Jacques-de-l'Achigan. Those two territories were then merged one again, in 1998, for the creation of the current Saint-Jacques.
