Dodangeh Wildlife Sanctuary, with an area of 15,673 hectares, is located about 95 kilometers southeast of Sari city in Mazandaran province, and a very small part of its southeast is located in Semnan province. This area has rich and diverse ecological features, fauna, and flora. This research aimed to investigate the snake fauna of the area from April 2017 to late November 2017. After sampling, the samples were photographed, and after identifying the samples, their metric and meristic traits were measured. In total, 61 snake specimens were collected and 10 species from 10 genera and four families were identified, including: Dolichophis schmidti, Elaphe dione, Hemorrhois ravergieri, Platyceps najadum, Telescopus fallax iberus, Zamenis persicus from the Colubridae family, Natrix tessellata from the Natricidae family, Xerotyphlops vermicularis from the Typhlopidae family, Gloydius halys and Macrovipera lebetinus obtusa from the Viperidae family. Among the specimens, lily snake is semi-venomous; Caucasian viper and viper are venomous and the remaining species are non-venomous. The highest abundance is related to the species Zamenis persicus and the lowest abundance is related to the species Hemorrhois ravergieri and Xerotyphlops vermicularis. The family Colubridae with six species showed the highest diversity and the family Typhlopidae with one species showed the lowest diversity and number among the snakes of the region. During this study, no new record was reported from the Dondangeh Wildlife Sanctuary. Given the importance of its animals, measures should be taken to preserve its various species.
