Naja is a genus of venomous elapid snakes commonly known as cobras (or "true cobras"). Members of the genus Naja are the most widespread and the most widely recognized as "true" cobras. Various species occur in regions throughout Africa, Southwest Asia, South Asia, and Southeast Asia. Several other elapid species are also called "cobras", such as the king cobra (Ophiophagus hannah) and the rinkhals (Hemachatus haemachatus), but neither are true cobras, in that they do not belong to the genus Naja, but instead each belong to monotypic genera Hemachatus (the rinkhals) and Ophiophagus (the king cobra/hamadryad).
