Crotalus durissus, commonly known as the South American rattlesnake, is native to South America. Its geographical distribution includes countries such as Brazil, Argentina, Colombia, Venezuela, Paraguay, Bolivia, and Peru. It is primarily found in the central and northern parts of South America.

The typical habitat of Crotalus durissus consists of dry or xeric environments, including savannas, dry forests, and grasslands. These areas often have a seasonal climate, with distinct wet and dry periods.
