The Five West Sea Islands refers to the five islands in the West Sea administered by Incheon, South Korea. They are Yeonpyeongdo, Baengnyeongdo, Daecheongdo, Socheongdo and Soyeonpyeongdo. Their positions are much closer to North Korea as these islands are originally part of Hwanghae Province and their sovereignties are claimed by North Korea, but they are controlled by South Korea since the United Nations forces established the Northern Limit Line (NLL) north of the islands in 1953 following the Korean War.
