Marguerite-D'Youville (French pronunciation: [maʁɡəʁit djuvil]) is a regional county municipality located in the Montérégie region of southwestern Quebec, Canada. The seat is in Verchères.

The RCM was formerly named Lajemmerais Regional County Municipality, after Christophe du Frost de Lajemmerais, the father of Marguerite d'Youville. On February 12, 2011, the name was changed to honour d'Youville directly. However, Statistics Canada retained the name "Lajemmerais" for the 2011 census because the name change came after its reference date of January 1, 2011. Since the 2016 census, the name has correctly been displayed as "Marguerite-D'Youville."
