Ste. Marie Church is a Roman Catholic church on the West Side of Manchester, New Hampshire, in the United States. The church was founded to serve the needs of French-Canadian Catholic immigrants to New Hampshire. The Gothic Revival church building is a prominent feature on the Manchester skyline, and dominates the West Side skyline. The building is perched atop the plateau that makes up Rimmon Heights, and forms one of the focal points of the Notre Dame neighborhood, along with Lafayette Park across the street.
