The non-marine molluscs of Iran are a part of the molluscan fauna of Iran, which is part of the (wildlife of Iran).
Freshwater gastropods
27 freshwater gastropod species (37% of freshwater gastropod species in Iran) are endemic to Iran.
Species of freshwater gastropods of Iran include:
Neritidae
Neritina mesopotamica Martens 1879 - the first report in Iran was in 2001
Neritina cinctellus (Martens, 1874) Neritina euphratica Mousson, 1874 Theodoxus jordani (Sowerby I, 1836) Theodoxus major Issel, 1865 - mentioned by Glöer & Pešić (2012) as Theodoxus lituratus (Eichwald, 1838) Theodoxus pallidus Dunker, 1861
Viviparidae

Melanopsidae
Melanopsis costata (Olivier, 1804) Melanopsis doriae Issel, 1865 Melanopsis kotschyi Philippi, 1847 Melanopsis sp. - Mansoorian (2001) listed Melanopsis from Iran as Melanopsis nodosa Mousson, 1874 and as Melanopsis praemorsa (Linnaeus, 1758), but Glöer and Pešić (2012) claimed that there are nine possible names for this species and that further study is necessary to establish under which name or names the Iranian populations should be placed.
Potamididae
Cerithidea cingulata (Gmelin, 1790)
Thiaridae
Thiara scabra (O.F. Müller, 1774) Melanoides tuberculata (O. F. Müller, 1774)
Bithyniidae
Bithynia tentaculata (Linnaeus, 1758) - This species most probably does not occur in Iran. Bithynia forcarti Glöer & Pešić, 2012 Bithynia starmuehlneri Glöer & Pešić, 2012 Bithynia mazandaranensis Glöer & Pešić, 2012 Bithynia cf. ejecta Mousson, 1874 Bithynia rubens (Menke, 1830) - questionable taxonomic status Bithynia sistanica (Annandale & Prashad, 1919) Pseudobithynia irana Glöer & Pešić, 2006 Pseudobithynia zagrosia Glöer & Pešić, 2009

Radix persica (Issel, 1865) Radix auricularia (Linnaeus, 1785) - Radix auricularia gedrosiana Annandale & Prashad, 1919 Radix bactriana (Annandale & Prashad, 1919) Radix iranica (Annandale & Prashad, 1919) Radix gedrosiana (Annandale & Prashad, 1919) - Radix gedrosiana gedrosiana (Annandale & Prashad, 1919). Radix gedrosiana rectilabrum is endemic to Iran. Radix hordeum (Mousson, 1874) 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.
