Ten species of Uroleucon (Uroleucon) Mordvilko, 1914 are recognized from the Korean Peninsula, among which three species, U. (Uroleucon) exiguum, U. (U.) asteriae and U. (U.) leontopodiicola are described as new to science. U. (U.) cichorii is recorded for the first time from the Korean Peninsula. A key to the subgenera of Uroleucon and species of the subgenus Uroleucon occurring in Korea is presented.
