The Church of St. Joseph is a former Roman Catholic church building in the unincorporated community of Elmer, Minnesota, United States. It was built in 1913 by the Duluth and Iron Range Railroad as a bonus to settlers the company had recruited to buy its surplus land. The Church of St. Joseph was listed on the National Register of Historic Places in 2002 for its local significance in the theme of exploration/settlement. The nomination includes the associated cemetery, located across the road to the east. The property was nominated for illustrating the corporate efforts to settle northern Minnesota once it had been cleared of valuable timber.
