Gyeonggi-do (Korean: 경기도, Korean pronunciation: [kjʌ̹ŋ.ɡi.do̞]) is the most populous province in South Korea. Its name, Gyeonggi, means "京 (Seoul) and 畿 (the area around Seoul)". Thus, Gyeonggi-do can be translated as "Seoul and the surrounding areas of Seoul". Seoul, the nation's largest city and capital, is in the heart of the area but has been separately administered as a provincial-level special city since 1946. Incheon, the nation's third-largest city, is on the coast of the province and has been similarly administered as a provincial-level metropolitan city since 1981. The three jurisdictions are collectively referred to as Sudogwon and cover 11,730 km2 (4,530 sq mi), with a combined population of 25.5 million—amounting to over half of the entire population of South Korea.
