Paul Chabanaud was a French ichthyologist and herpetologist.
Beginning in 1915, he worked as a volunteer under zoologist Louis Roule at the Muséum National d'Histoire Naturelle in Paris. In 1919–1920, he undertook a scientific expedition to French West Africa on behalf of the museum, during which he collected thousands of zoological specimens. Following his return to Paris, he served as a preparator in the laboratory of biologist Jean Abel Gruvel at the museum. He specialized in the anatomy and systematics of the flatfish and was the taxonomic authority of many herpetological and ichthyological species.
