Masaaki Morisita (森下正明光) (27 January 1913 - 25 February 1997) was a Japanese ecologist and professor emeritus of animal ecology at Kyoto University. He is known as the father of population ecology in Japan. Morisita's overlap index and Morisita's index of dispersion are named after him. In addition to his work on statistical ecology, he also studied the natural history of Japanese ants. With several other myrmecologists, he produced a complete catalogue of ants in Japan. Three species of ants are named after him (Pyramica morisitai, Proceratium morisitai , and Lasius morisitai).
