Franz Heinrich Kleinschmidt (1812–1864) was a German missionary and linguist who worked in southern Africa, now in the region of Namibia. He founded the missionary station and town of Rehoboth and together with Carl Hugo Hahn set up the first Rhenish mission station to the Herero people in Gross Barmen. Kleinschmidt is known for his scientific work on the Nama language.
