The Sanxia River () is a tributary of the Dahan River in New Taipei City, northern Taiwan.依據 三峽鎮志第一章《地理》：總計三峽溪幹流長約二八·五公里，較日治時期二三公里增長四公里餘，蓋河道變遷，注入口北移所致 The Sanxia is long, with a drainage basin. The river flows through Tucheng District, Shulin District and a small portion of Daxi District in Taoyuan City.
