The Josutu League (Mongolian: ǰosutu-yin čiɣulɣan,) 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.
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 in 1933 by the Manchukuo government. Its territory is now distributed among the modern administrative regions:
There remain two Mongol autonomous counties in Liaoning.
