A brief survey of literature and original data, and also comprehensive results on study of algae diversity in Central Asia water bodie s are given. There are 2722 species and inters pecies of different taxonomic groups were fou nd in Central Asia (Tajikistan, Uzbekistan, K irgizstan, Turkmenistan), and in south Kazakhstan water bodies were found. In Tajikistan and in Uzbekistan reservoirs are studied better then in all other Central Asia states. 2722 spe cies and interspecies of algae belong to 423 gen era, more than 100 families and 12 divisions: Cyanophyta (Cyanobacteria), Euglenophyta, Cryptophyta, Dinophyta, Chrysophyta, Xanthophyta, Bacillariophyta, Chlorophyta, Strept ophyta, Charophyta, Glaucophyta, Rhodophyta. Among them Bacillariophyta, Chlorophyta, Cyanophyta and Streptophyta more distributed in water bodies of Central Asia and represented more than 300-500 species and interspecies in each division. Central Asia territory is divid ed on several botanical-geographical regions: Pa mir-Alay, Syrdariynsky, Amydariynsky, Aral-Kaspiysky, Aral Sea, Kyzyl-Kumsky, Karakum sky and Tien-Shansky. The greatest number of Algae – more than 1500 species was found in Pa mir-Alay, Syrdariynsky and Amydariynskyregions. Flora of the Central Asia Algae in botanical-geographical analysis demonstrates to be genetically dissimilar and involves different elements of flora: boreal, boreal-mountain, ne moral, ancient Mediterranean and multiregional. Slightly expressed endemism of algae (1.5%) and prevalence of boreal and multiregional elements (24-35%), testify that allokhtone elements had penetrated from Siberia and China play an important role in the origin of algae flora of the C entral Asia.
