Seitarō Gotō (1867–1935) was a Japanese scientist, known for his works on the Monogenea,[1][2] a class of parasitic flatworms which are ectoparasites of fishes.

After his return to Japan in 1896, he became professor at Daiichi High School.

In 1920, he was appointed head of the University of Tokyo's Department of Science.

Several taxa were named in honour of Seitarō Gotō.

These include the genus Gotocotyla Ishii, 1936 and the family Gotocotylidae Yamaguti, 1963[6] (Monogenea).
