We report Fimbristylis ovata (Burm.f.) J. Kern (Cyperaceae) from the sunny grasslands along the coastline on Jejudo Island, Korea, as a new distribution in Korea. This is thought to be the third confirmed record of this rare sedge in Korea; the first was from Gapari ('Is. Quelpaert') collected by Taquet in 1908, and the second was from Marado Island, collected by Kim and Kim in 2018. We found two new populations on Jejudo Island, the first with many individuals and the second with only a few plants. Following an examination of herbarium specimens, this species is considered to be rare and endangered in Korea, limited in distribution in Korea to Jejudo and Marado Islands.
