The Liu River (, pinyin: Liu Jiang, literally: Willow River) is a tributary within the Pearl River system in Guangxi, China. It is formed by the confluence of the Rong and Long rivers in Fengshan. It flows south through Liuzhou and is joined by the Luoqing Jiang to the south. It meets the larger Hongshui He east of Laibin where it becomes known as the Qian Jiang.
