Abstract: Study research aims to study freshwater biodiversity of Mollusca at Euphrates River, Iraq. Four sites were chosen during a period of 6 months (from December, 2016 to May, 2017). Physiochemical properties of Euphrates River were measured, e.g. (water temperature, pH, Electrical Conductivity (EC), Total Dissolved Solid (TDS), salinity, alkalinity, total hardness, Calcium ion (Ca2+), Magnesium ion (Mg2+), dissolved oxygen, biological oxygen demand and chloride) total organic carbon and organic matter in sediments. Eight species were classified, the dominate species were found to be Corbicula fluminea and Melanopsis nodosa while Pseudodontopsis euphraticus was showed to be at January, 2017. Shannon’s diversity index recorded higher value in site 2 at near Imam Ali bridge during January, 2017. Pielou’s evenness was recorded the highest record in site 4 (under the Cement Plant Bridge) during February and Margalef index in site 1 (North of Imam Ali bridge about 1 km) during December, 2016 about (2.46). Some of the physicochemical properties had positive or negative relationship with the numbers of species, others had a reversed relation.
