- Numerous animal species naturally produce chemical toxins which are used to kill or incapacitate prey or as a defense against predators. Venomous animals actively deliver their toxins (called venom) into their target through a specially evolved mechanism, such as a bite or sting, by using a venom apparatus, such as fangs or a stinger, in a processes called envenomation. They are often distinguished from poisonous animals, which instead passively deliver their toxins (called poison) to their victims upon contact such as through inhalation, absorption through the skin, or after being ingested. The only difference between venomous animals and poisonous animals is how they deliver the toxins. This list deals exclusively with venomous animals. Venoms have evolved to serve a wide variety of purposes. Their intended effects can range from mild fleeting discomfort to paralysis and death, and they may be highly selective in which species they target, often making them harmless to all but a few specific co-evolved organisms; what may be fatal to one species may be totally insignificant to another species. Because the definition of "venomous" can be extremely broad, this list includes only those animals with venom that is known or suspected to be medically significant for humans or domestic animals.

- Cette liste d'animaux venimeux recense les espèces animales généralement considérées comme les plus dangereuses du fait du venin qu'ils peuvent injecter à leurs victimes. Ces espèces animales sont très variées, incluant reptiles, arachnides, céphalopodes, méduses, poissons, insectes, mammifères, voire dinosaures (tel que le Sinornithosaurus, pour lequel certains chercheurs ont émis l'hypothèse qu'il était venimeux). Plusieurs espèces parmi les plus dangereuses vivent en Australie ou dans ses environs immédiats. (fr)
