The Andaman cobra (Naja sagittifera) is a venomous elapid snake native to the Andaman Islands, a small island chain in the Bay of Bengal just west of Myanmar. It grows to a maximum length of 1.5 metres.

This nocturnal snake lives in forests, on forest edges and in mangrove swamps. It is frequently found close to water. It feeds mainly on small mammals and frogs, but will also take a variety of rodents, birds and bird eggs.

The Andaman cobra's venom consists mostly of a post-synaptic neurotoxin, but also contains anticoagulants.
