An overview of the genus Rhaponticum Vaill. is presented, as growing on the vast territory of Kazakhstan. The study is based on field ma-terials, literature and accurate revision of herbarium materials. Data from more than 240 herbarium specimens stored in herbarium collections were analyzed: LE, AA, MW, TASH, KUZ, KG, NUR and MANG. The article provides illustrations and data on the general distribution, ecological occur-rence, phenology and environmental status of Rhaponticum species growing in Kazakhstan. In addition, detailed distribution maps and taxonomic keys for each species have been compiled. In total, 6 species of Rhaponticum grow in Kazakhstan, 3 of which (Rh. carthamoldes, Rh. aulieatense and Rh. karatavicum) are included in the red book of Kazakhstan. According to the results obtained, the most common species in Kazakhstan are Rh. altaicum (57 locations in 13 Floristic Regions (FR)) and Rh. nitidum (56 locations in 9 FR). As a result of the conducted research Rh. nitidum was first found on the territory of Northern Usturt, Rh. altaicum was discovered on the Tarbaga-tai. Also, the growth of Rh. altaicum in the Eastern Upland, Bukeev floristic region and Ulutau are not confirmed by herbarium materials. These species were relatively rare: Rh. carthamoldes (32 locations in 3 FR), Rh. aulieatense (12 locations in 2 FR) and Rh. karatavicum (27 locations in 1 FR). Rh. na-manganicum (found only in two localities in the Western Tien Shan) is rec-ommended for inclusion in the next edition of the Red Book of Kazakhstan. According to the data obtained, further study of the number and status of populations of Rhaponticum species on the territory of Kazakhstan is required to revise their conservation status.
