Youjian Jianghu (游劍江湖), literally Wandering Swordsman in the Jianghu, is a wuxia novel by Liang Yusheng. It was first published as a serial between 1 July 1969 and 4 February 1972 in the Hong Kong newspaper New Evening Post. The novel is also known by an alternative title, Tan Jia Ge (彈鋏歌; "Ballad of the Strummed Sword").
Set in 19th-century China during the Qing dynasty, the story follows martial artists who become entangled in struggles involving loyalty, love, and rebellion in the wulin. The novel is the first instalment in a tetralogy that concludes Liang Yusheng's Tianshan series, continuing from after Xiagu Danxin. It is followed by Muye Liuxing, Tanzhi Jinglei, and Juesai Chuanfeng Lu. Critics have described Youjian Jianghu as one of Liang Yusheng's more introspective later works, and a representative example of the development of the "cultured swordsman" (文士型侠客) archetype in modern wuxia literature.
