The U.S. Geological Survey records Weldon as a populated place. Its GNIS reference point is listed under the county label St. Charles County, Missouri, on the Weldon Spring map. This identifies a geographic reference point, not the full community boundary, current administrative boundaries, or its legal incorporation status. Use the locality and county references below when checking an address or distinguishing similarly named places.
Nearby places are within 15 miles straight-line, not driving distances. They retain their own locality ownership and are not claimed to be inside this community.
