The updated checklist of liverworts of the Komi Republic (Russia) is presented. It includes 187 species, four subspecies, nine varieties belonging to 74 genera, 37 families, 10 orders (Blasiales, Calobryales, Fossombroniales, Jungermanniales, Marchantiales, Metzgeriales, Pallaviciniales, Pelliales, Porellales, Ptilidiales), three classes (Haplomitriopsida, Marchantiopsida, and Jungermanniopsida). The floristic checklist was augmented with 27 taxa (14 % of all known flora) including 23 species, two subspecies and two varieties. In the nearby territories (Nenets, Yamalo-Nenets, Khanty-Mansi Autonomous Districts, Arkhangelsk, Vologda and Kirov Regions, Perm Krai), 48 taxa of liverworts and hornworts are known, which may occur in the Komi Republic, too. The taxonomic diversity of the known flora is probably 80-90 % of the real size. The territories promising for research are southern areas of the republic (upper reaches of the Kobra, Luza and Sysola rivers), polar regions of Bolshezemelskaya tundra and the Polar Urals, as well as the Subpolar and Northern Urals. The flora contains 26 liverwort species red-listed in the Komi Republic, among them Ave species (Cephaloziella integerrima, Haplomitrium hookeri, Nardia breidleri, Oleolophozia perssonii, and Protolophozia elongata) listed in the Red Data Book of the Russian Federation (plants and fungi).
