Porthidium dunni is a species of venomous pitviper in the family Viperidae. The species is endemic to Mexico. There are no recognized subspecies. [4]
The specific name, dunni, is in honor of American herpetologist Emmett Reid Dunn [5] "in appreciation of his work on American snake fauna". [6]
Adults of P. dunni are usually 30–40 cm (11+3⁄4–15+3⁄4 in) in total length (including tail), with a maximum of 57 cm (22+1⁄2 in). A moderately stout and terrestrial species, the tip of the snout is moderately elevated. [3]
P. dunni is found in southern Mexico in the Pacific lowlands of Oaxaca and western Chiapas. [7]
The type locality given is "the immediate vicinity of the village of Tehuantepec" [Oaxaca, Mexico]. [2]
P. dunni is ovoviviparous. [7]
The species P. dunni is classified as Least Concern (LC) on the IUCN Red List of Threatened Species (v3.1, 2007). [1] 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. The population trend is stable. Year assessed: 2007. [8]

Porthidium is a genus of venomous pitvipers found in Mexico and southward to northern South America.
