The Josutu League (Mongolian: ǰosutu-yin čiɣulɣan, ᠵᠣᠰᠤᠲᠤ ᠶᠢᠨ ᠴᠢᠭᠤᠯᠭᠠᠨ Chinese: 卓索圖盟; pinyin: Zhuōsuǒtú Méng) was the southernmost league of Inner Mongolia during Qing rule.
It occupied land that forms part of the modern-day Chinese provinces of Liaoning, Hebei, and Chifeng in China's Inner Mongolia.
The name of Josutu was named after a place in the Tumed Right (wing) Banner (not Tumed Right Banner), where Mongol princes regularly gathered together to administer inter-banner affairs.
The Josutu League consisted of two ayimag or five banners.
Its territory is now distributed among the modern administrative regions: There remain two Mongol autonomous counties in Liaoning.
