The round hickorynut is found in the Ohio, Tennessee and Cumberland drainages. Its northern range includes the Lake Erie drainage in Michigan, east to western New York and western Pennsylvania. In the south it is found in the Tombigbee drainage, including northern Alabama. Its western range is from eastern Arkansas to southeastern Illinois.

In Michigan the records for this species are mainly in the Belle, Clinton, Huron and Raisin drainages as well as Lakes St. Clair and Erie. One specimen is recorded from the Grand River (probably pre-1920s), however the data are scant and this species has not been found in subsequent intense surveys on the Grand and its drainages.
