The Josutu League (Mongolian: ǰosutu-yin čiɣulɣan жосуту-йин чиулан, 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 Banner, where Mongol princes regularly gathered together to administer inter-banner affairs.
The Josutu League consisted of two ayimag or five banners.
In addition, the Khalkha Banner (Tangghud-Khaklha Banner) was split from the Tümed Left Banner in 1913 under the Republic of China.
The league was dissolved and its territory was distributed among the modern administrative regions:
There remain two Mongol autonomous counties in Liaoning.
