Sandaowan is a town in Yanji, the capital city of the Yanbian Korean Autonomous Prefecture in Jilin Province, China. It lies within the administrative territory of Yanji rather than being a separate county-level city, and it forms one of the town-level divisions under the city's jurisdiction.
The town covers a total area of 555.7 square kilometres and has a total population of 9,944. Its administrative structure comprises two communities and nine villages. The communities are Canchang Community and Meikuang Community, while the villages are Zhongxin, Wudao, Nanzhangzhi, Beizhangzhi, Donggou, Pinggang, Tuntian, Zhibian and Lishu.
Sandaowan's large land area relative to its small population reflects the predominantly rural and sparsely settled character of much of the town, which is organised into a small number of community-level units alongside its village subdivisions.
