'''Seoul Subway Line 5''' of the [[Seoul Metropolitan Subway]], dubbed ''the purple line'', is a long line crossing from west to the east across the [[Seoul National Capital Area]], [[South Korea]]. It is one of two subway lines in Seoul to cross ''under'' the [[Han River (Korea)|Han River]] (the other being the [[Suin-Bundang Line]]), which is done at two points (between Mapo and Yeouinaru, and also between Gwangnaru and Cheonho). The main line runs through to [[Hanam Geomdansan station|Hanam Geomdansan Station]] while the branch line from [[Gangdong station|Gangdong Station]] terminates at [[Macheon station|Macheon Station]]. In 2019, Line 5 carried an annual ridership of 334 million or about 915,000 passengers per day.<ref>{{Cite web|title=서울시 지하철수송 통계|url=http://data.seoul.go.kr/dataList/273/S/2/datasetView.do#none|access-date=21 May 2021|website=data.seoul.go.kr|language=ko}}</ref>
