Townships are also of value for historical purposes in terms of genealogical research. Each town or city is within one or more townships in an Arkansas county based on census maps and publications. The townships of Columbia County are listed below; listed in parentheses are the cities, towns, and/or census-designated places that are fully or partially inside the township.
