The non-marine molluscs of Iran are a part of the molluscan fauna of Iran, which is part of the (wildlife of Iran).
27 freshwater gastropod species (37% of freshwater gastropod species in Iran) are endemic to Iran.

Thiara scabra (O.F. Müller, 1774)
Melanoides tuberculata (O. F. Müller, 1774)

Radix labiata (Rossmaessler, 1835)
Galba truncatula (Müller, 1774)
Galba schirazensis Küster, 1862
Stagnicola sp. - Most probably, the species reported from Iran as Stagnicola palustris represents an undescribed species. It is not possible to identify or eventually describe this species according to shells only as new to science without anatomical studies.
Lymnaea stagnalis (Linnaeus, 1774)
Doubtful Lymnaeidae:
Radix lagotis (Schrank, 1803) - It was recorded from Iran by Martens (1874) and by Biggs (1937), but this species most probably does not occur in Iran.

Freshwater species excluded from the list:
Bithynia badiella (Küster, 1852)
Bithynia troschelii (Pasch, 1842)
Acroloxus lacustris (Linnaeus, 1758) - It was recorded by Lothar Forcart in 1935. But an analysis of the two specimens from Forcart’s collection (NMB 11516a) identified as Acroloxus lacustris from Mazandaran Province shows that these specimens belong to Acroloxus pseudolacustris.
