The western diamondback rattlesnake^[3] or Texas diamond-back^[4] (Crotalus atrox) is a rattlesnake species and member of the viper family, found in the southwestern United States and Mexico. Like all other rattlesnakes and all other vipers, it is venomous. It is likely responsible for the majority of snakebite fatalities in northern Mexico and the greatest number of snakebites in the U.S.^[5] No subspecies are currently recognized.^[3]

It lives in elevations from below sea level up to 6,500 feet (2,000 m). This species ranges throughout the Southwestern United States and northern half of Mexico. Currently, western diamondback rattlesnakes are not threatened or endangered.
