Cerrophidion is a genus of pit vipers which are endemic to southern Mexico, Central America, and western Panama.

[1] The generic name, Cerrophidion, is derived from the Spanish word cerro, which means "mountain", and the Greek word ophidion, which means "small snake".

The head scalation is highly variable, with some scales being enlarged, especially in the frontal region.

The fact that the prelacunal is not fused with any of the supralabial scales is characteristic for this genus.

[2] Cerrophidion species are found in southern Mexico (in the highlands of the Mexican states of Guerrero and southeastern Oaxaca), southward though the highlands of Central America (Guatemala, El Salvador, Honduras, northern Nicaragua and Costa Rica) to western Panama.
