The results of the analysis of literature and original data on the species diversity and distribution patterns of algae of the genus Nitella C.Agardh (Charophyta, Charales) in Ukraine are presented. Now, the diversity of the genus Nitella in Ukraine is represented by 9 species out of 13, known in the Europe flora of Charales, namely: Nitella capillaris (Krock.) J.Groves et Bull.-Webst., N. confervacea (Bréb.) A.Braun ex Leonh., N. gracilis (Sm.) C.Agardh, N. flexilis (L.) C.Agardh, N. mucronata (A.Braun) Miq., N. opaca (C.Agardh ex Bruz.) C.Agardh, N. syncarpa (Thuill.) Chev., N. tenuissima (Desv.) Kütz. and N. translucens (Persoon) C.Agardh. An annotated list of Ukrainian species in Ukraine. A total of 78 locations have been registered, including historical, lost, and modern ones. Most of them were found within the Pripyat-Desnianska (PpDSAP) (50) and Serednyodniprovska (SDpAP) (21), much less  within the Dnieper-Black Sea (DpAp) (3) and Carpathian-Danube (CpDnAP) (4) algofloristic subprovinces. It is suggested that main limiting factors influencing on diversity and distribution patterns of the Nitella species in Ukraine are the type of waterbodies, temperature, a degree of minimalization as well as chemical main ionic composition of water and active reaction (pH) of water.
