The eastern brown snake (Pseudonaja textilis), often referred to as the common brown snake, is a highly venomous snake of the family Elapidae, native to eastern and central Australia and southern New Guinea. It was first described by André Marie Constant Duméril in 1854. The adult eastern brown snake is up to 2 m (7 ft) long with a slender build. Its variable upper parts can be several shades of brown, ranging from pale brown to almost black, while its underside is pale cream-yellow, often with orange or grey splotches. The eastern brown snake is found in most habitats except dense forests. It has become more common in farmland and on the outskirts of urban areas, benefiting from agriculture due to the increased numbers of its main prey, the introduced house mouse. The species is oviparous. The snake is considered to be a least-concern species according to the International Union for Conservation of Nature (IUCN), though its status in New Guinea is not well known.
