Max Hartmann (7 June 1876 – 11 October 1962) was a German biologist, alluded to in the book Phylogenetic Systematics by Willi Hennig for his investigations into divisions of sciences, most notably into descriptive and explanatory. He was a philosopher of science and the author of Allgemeine Biology.

The publicly available abstract of an article in Nature Magazine (1946) presents him, as a student of the sexuality and fertilization in Protozoa and Algae; that "he can look back upon a fine record of original research... His investigations of ‘relative sexuality’ [which] have led to very important biochemical studies of the substances produced and released by gametes and essential for fertilization in Algae, echinoderms, molluscs and fishes"; and that he was an outspoken critic of Nazism. Hartmann was director of the Kaiser Wilhelm Institut für Biologie.
