The Belcher Mound Site (16CD13) is an archaeological site in Caddo Parish, Louisiana. It is located in the Red River Valley 20 miles north of Shreveport and about one-half mile east of the town of Belcher, Louisiana. It was excavated by Clarence H. Webb from 1959 to 1969. The site gives its name to a local phase of the Caddoan Mississippian culture, the Belcher Phase, which radiocarbon dates suggest lasted from 1400 to 1600 CE.
