Seven species of the genus Grapholita Treitschke, 1829 are recognized from Korea. Among them, G. funebrana (Treitschke) and G. sp. 1 are reported for the first time from Korea. The previously cited species with uncertainty of its distribution in the Korean peninsula, G. inopinata Heinrich, has not been found, and thus determined absent in the Republic of Korea. All the known species are redescribed with illustrations of adults, including genitalia of both sexes. Their known host plants are also listed. A key to the species of the genus, based on external and male genitalic characters, is given.
