Daebu Island (, Deabudo) is an island in the Yellow Sea, within the municipal borders of Ansan city, Gyeonggi province. It has a population of roughly 7,114 people and an area of 41.98 km². Due to rising mudflats, the island has merged with neighbouring Seongam-do ( Hangeul:선감도) and Tan-do (탄도). Administratively, the island today is divided into five dong: Daebubuk-dong (대부북동), Daebunam-dong (대부남동), Daebudong-dong (대부동동), Seongam-dong (선감동) and Pungdo-dong (풍도동). The predominant industries are tourism and fishing. The island is connected (via Seongam-do and Tan-do) to the mainland in the south-east by road bridges, to Hyeong-do (형도) (and thence the mainland) in the north-east by several routes due to land reclamation efforts, and to Seonjae-do (선재도) (and thence Yeongheung Island (영흥도) and others) to the west by a further road bridge.
