Marine File Snake or Little File Snake (Acrochordus granulatus) is a species of snake in family Acrochordidae. This species is suspected to be parthenogenetic.

These snakes inhabit brackish estuaries, and have been found at sea. They are fully aqautic snakes unable to function outside of water and have thin skin which rips easily. However the skin is file-like, which is where their common name comes from. This is used for the purposes of underwater constriction, the acrochord's primary method of obtaining and killing prey. Females of the family are ambush predators while males actively forage. They are sexually dimorphic, males being much smaller and having higher contrast.

This species is found in waters around China (Hainan), New Guinea, Solomon Islands, Australia (along the coast of North Territory, Queensland, West Australia), Indonesia (Ambon, Flores, Irian Jaya, Java, Jobi, Schouten, Sulawesi, Sumatra, Ternate, Timor, We); Bangladesh; Cambodia; India (including Nicobar Islands); Malaysia (Malaya and East Malaysia); Myanmar (Burma); Philippine Islands (including Palawan: Calamian Islands, Panay); Singapore; Sri Lanka, Thailand; Vietnam. Papua New Guinea (including many satellite islands).

This snake is found mainly in water bodies like small ponds, swamps and estuaries.

According to Shine, 50% of the acrochords tested for stomach contents yielded either rainbow fish, grunters, cat fish or sleepy cod. There is no evidence suggesting that they feed on amphibians. Occasionally known to eat eels.

Parthenogenetic reproduction occurred once in a pair of A. arufurae.
