Jules Bourgeois (31 May 1847, Sainte-Marie-aux-Mines – 18 July 1911) was a French entomologist who specialised in Coleoptera.
The French Academy of Sciences awarded him the Prix Thore for 1908 in recognition of his work on Chrysomela.
Jules Bourgeois was initially associated with his father and brother in Rouen, as the Paris representative of the family weaving business (1881-1889) and later worked at the spinning mills of H.
Schwartz in Sainte Marie-aux-Mines from 1893.
He used his leisure time to follow his true vocation, that of a naturalist.
Bourgeois studied coleoptera then included in the then group Malacodermata, now unranked (Elateroidea (in part), Lymexyloidea, Cleroidea, Tenebrionoidea).
