The Persian ratsnake (Zamenis persicus) is a species of medium-sized nonvenomous snake in the family Colubridae.

Z. persicus is found in temperate northwestern Iran and Azerbaijan, in the area near the Caspian Sea.

Z. persicus has habits very similar to Z. situla and for many years it was considered a subspecies of Elaphe longissima.

The Persian ratsnake is principally regarded as a terrestrial species, spending most of its time in the leaf litter; however, it is also an agile climber and will mount low brush.

Sexually mature female Persian ratsnakes lay clutches of 4–8 eggs, which hatch after 45–55 days of incubation.
