We investigated the flora of Yeoseo-do (N $33^{\circ}58^{\prime}$, E $126^{\circ}55^{\prime}$), located in Wando-gun, Jeollanam-do, South Korea and discussed the vascular plants found there. Four separate field trips were completed from April to October of 2013. The vascular plants were summarized as 463 taxa; 112 families, 306 genera, 409 species, 6 subspecies, 42 varieties, 5 forms and 1 hybrids. The number of endemic species of Korea were 6 taxa, and 12 taxa designated by the Ministry of Environment as red data of endangered vascular plants were investigated in this region. There were a total of 98 taxa of floristic regional indicator plants and one taxon of level I endangered species, Neofinetia falcata (Thunb.) Hu, as designated by the Ministry of Environment. 33 taxa have shown their southern distributional limit ranges, and 10 taxa of halophytes were confirmed in the Yeoseo-do (Isl.). In additon, 27 taxa of the naturalized plants were recorded.
