The parish municipality of Saint-Alban () is a former parish now part of the current municipality of Saint-Alban, Quebec, Canada.
Prior to January 17, 1991, the parish of Saint-Alban was an independent municipality; on that date, it and the village of Saint-Alban were merged into the new municipality of Saint-Alban.
The sector was originally part of Deschambault. In 1860, the sector became an independent municipality under the name of Saint-Alban-d'Alton. In 1918, a part of its territory was taken for the creation of Saint-Marc-des-Carrières. The same year, the more urban sector split to became the village municipality of Saint-Alban. Those two territories were then merged once again, in 2012, for the creation of the current Saint-Alban.
