Cerrophidion tzotzilorum is a venomous pit viper species which is native to southern Mexico. There are no subspecies that are recognized as being valid.
The specific name, tzotzilorum (Latin genitive plural), is in honor of the Tzotzil people.
C. tzotzilorum is terrestrial and moderately stout. Adults probably do not exceed 50 cm (19.5 in) in total length (including tail).

The species C. tzotzilorum is classified as Least Concern (LC) on the IUCN Red List of Threatened Species (v3.1, 2001). Species are listed as such due to their wide distribution, presumed large population, or because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
