Otto Karl Friedrich Schoetensack (; 12 July 1850 in Stendal – 23 December 1912 in Ospedaletti) was a German industrialist and later professor of anthropology, having retired from the chemical firm which he had founded. During a 1908 archeological dig, he oversaw the worker Daniel Hartmann who found the lower jaw of a hominid, the oldest human fossil then known, which Schoetensack later described formally as Homo heidelbergensis.
