The Daejeoncheon (Korean: 대전천; Hanja: 大田川) is a national river of South Korea within the Geum River system, and one of the three major rivers (including Gapcheon and Yudeungcheon) that flow through Daejeon. The river originates within Daejeon, at Mr. Manin and Mt. Bipa, approximately 15 km (9 mi) to the south of the city center, and flows to the north through the city's old downtown, dividing the districts of Jung-gu and Dong-gu, before merging with the Yudeongcheon river.[1][2]
