Nicolaus Kleinenberg (11 March 1842, in Libau – 5 November 1897, in Naples) was a Baltic German zoologist and evolutionary morphologist.
He studied at the University of Jena under Ernst Haeckel, obtaining his doctorate for studies of embryo cleavage in Hydra. His later work Hydra - Eine anatomisch-entwicklungsgeschichtliche untersuchung, in English "An anatomical-evolutionary investigation of Hydra" (Leipzig, Wilhelm Engelmann, 1872) is a classic, still quoted monograph which has implications for evolution theory.
Kleinenberg was a close friend of Anton Dohrn, helping him to found the marine station at Messina, where he was professor. He worked with Ilya Ilyich Mechnikov and Rudolf Ludwig Karl Virchow on their visits to Messina. Kleinenberg and Hugo Eisig were the first assistants at Stazione Zoologica in Naples.
