René Oberthür (1852, Rennes – 27 April 1944) was a French entomologist who specialised in Coleoptera. With his brother Charles Oberthür he worked in "Imprimerie Oberthür" the very successful printing business founded by his father François-Charles Oberthür. René and Charles supplied free bibles, missals, catechisms and other printwork to missionaries in exchange for insect specimens. In addition they purchased on a large scale, acquiring almost all the large collections sold during their lifetime.
