The diatoms of the thermal and mineral waters of the Pamir were represented by 138 species, and 163 infraspecific taxa as a result of our research of six mineral and thermal springs and analysis of references data. The vast majority of them are common species that live in different types of water bodies. The prevalence of sutural forms of the class Bacillariophyceae, preferred to habitation on the substrate, was revealed. The predominance of representatives of the families Naviculaceae (18 species), Cymbellaceae (18 species), the genera Navicula, Cymbella, and Nitzschia was revealed in the total composition of diatoms of the studied springs of Pamir. In total, 22 new species were found for the Pamir Mountains. The high individuality of the species composition of the floras of the studied sources is revealed. The complete list presented in this study will serve as a basis for characterizing the inhabitants represented the specially protected natural territories of the Pamir.
