# List of islands of South Korea

The following is a list of major islands of South Korea, the Republic of Korea, arranged by body of water and then by province.
South Korea is mostly surrounded by water and has 2,413 kilometres (1,499 mi) of coast line along three seas; to the west is the Yellow Sea (called Sohae Korean: 서해; Hanja: 西海; in South Korea, literally means west sea), to the south is the East China Sea, and to the east is the East Sea (Sea of Japan) (called Donghae Korean: 동해; Hanja: 東海; in South Korea, literally means east sea). Geographically, South Korea's landmass is approximately 100,032 square kilometres (38,623 sq mi).
South Korea occupies the southern portion of the Korean Peninsula, and has more islands than North Korea. Most of the islands of South Korea are on its west and south coast. South Jeolla Province has the most islands among South Korea and Korean peninsula. Other well known islands of South Korea are Jeju Island, Dokdo, Geojedo, Marado, and Heuksando for tourism.
In accordance with the Constitution of South Korea, all of the islands controlled by the DPRK are wholly claimed by the ROK. On the other hand, according to the Constitution of the Democratic People's Republic of Korea, all of the islands controlled by the ROK are wholly claimed by the DPRK. This causes the tension between North and South Korea with islands such as Baengnyeongdo.
Generally, name of islands of South Korea have do or seom at the end of the word. These notable two words mean island or islet in Korean language. For example, Jeju-do means Jeju Island and Hyeongjaeseom means Hyeongjae island.
