Moselle is an unincorporated community in Franklin County, Missouri, United States, and is largely abandoned. It is located about five miles northeast of St. Clair. The community was incorporated as a town in 1860 (having since being disincorporated) and is named after the Moselle River or Moselle département in France.
The town had a depot of the St. Louis-San Francisco Railway, and was a shipping point for the Moselle Iron Works, located about a mile southeast, on the banks of the Meramec River. The Moselle Iron Furnace Stack, active 1825-1849, is on the National Register of Historic Places.
Correction: The incorporation information listed in this article is not correct. The town was laid out in 1859 but was not incorporated until 1897. Source: Franklin County Tribune, 16 July 1897. Contributed by Sue Blesi.
