The Red-bellied Black Snake (Pseudechis porphyriacus) is a species of elapid snake native to eastern Australia. Though its venom is capable of causing significant morbidity, a bite from it is not generally fatal and less venomous than other deadly Australian snakes. It is common in woodlands, forests and swamplands of eastern Australia. It is one of Australia's best-known snakes, as it is common in urban areas along the eastern coast of Australia. It has an average total length of 1.5 to 2 metres.
