Crotalus pricei is a species of venomous snake, a pit viper in the family Viperidae.

[6] The specific name, pricei, is in honor of William Wightman "Billy" Price (1871–1922), a field biologist, who collected the first specimens which became the type series.

This is overlaid with a series of dorsal blotches that tend to be divided down the median line to form 39–64 pairs.

[4] Amid the mountain rocks where it lives, this small snake may rattle furiously at passing humans yet never be heard.

It has also been found in the Sierra Madre Oriental in southeastern Coahuila, Nuevo León, and Tamaulipas, with isolated records in San Luis Potosí and Aguascalientes.
