Achille Valenciennes (9 August 1794 – 13 April 1865) was a French zoologist.  
Valenciennes was born in Paris, and studied under Georges Cuvier. His study of parasitic worms in humans made an important contribution to the study of parasitology. He also carried out diverse systematic classifications, linking fossil and current species.
He worked with Cuvier on the 22-volume " Histoire Naturelle des Poissons " (Natural History of Fish) (1828–1848), carrying on alone after Cuvier died in 1832.  In 1832, he succeeded Henri Marie Ducrotay de Blainville (1777–1850) as chair of Histoire naturelle des mollusques, des vers et des zoophytes at the Muséum national d'histoire naturelle.
Early in his career, he was given the task of classifying animals described by Alexander von Humboldt (1769–1859) during his travels in the American tropics (1799 to 1803), and a lasting friendship was established between the two men.  He is the binomial authority for many species of fish, such as the bartail jawfish.
Working in the scientific field of herpetology, Valenciennes described two new species of reptiles. 
The organ of Valenciennes, a part of the anatomy of a female of the genus Nautilus , the purpose of which remains unknown, is named after him.
A species of lizard, Anolis valencienni , is named after him. 
Jean Léopold Nicolas Frédéric, Baron Cuvier, known as Georges Cuvier, was a French naturalist and zoologist, sometimes referred to as the "founding father of paleontology".

Histoire naturelle des poissons is a 22-volume treatment of ichthyology published in 1828-1849 by the French savant Georges Cuvier (1769-1832) and his student and successor Achille Valenciennes (1794-1865). It was a systematic compendium of the fishes of the world known at that time, and treated altogether 4 514 species of fishes, of which 2 311 were new to science. It is still one of the most ambitious undertakings in ichthyology ever. Most of the work appeared after the death of Cuvier. Later, Auguste Duméril still supplemented the work by two volumes in 1865 and 1870, which dealt mostly with groups that Cuvier had omitted, such as sharks.
