Walterinnesia is a genus of venomous snakes in the family Elapidae. The genus contains two species, known commonly as desert black snakes or black desert cobras, which are endemic to the Middle East. The generic name Walterinnesia honours Walter Francis Innes Bey (1858–1937), who was a physician and zoologist in Egypt.
The snakes are native to the Middle East, including the countries of Egypt, Lebanon, Syria, Jordan, Israel, Saudi Arabia, Kuwait, Qatar, Iraq and Iran.
These species occur in the desert (excluding completely sand deserts such as the ad-Dahna Desert). They can also be found in semi-desert scrubland and rocky terrain, extending into the foothills of vegetated Mediterranean terrain. They are also often found near human habitation in irrigated agricultural settlements.
