Jorightu Khan (Yesüder?) (1358–1392) was a Mongol Khan of the Northern Yuan dynasty based in Mongolia. There are questions about the identity of Jorightu: some scholars believe that Jorightu was Yesüder who was a descendant of Ariq Böke and that Engke Khan was Yesüder's son succeeding him, while other believe that the two were the same person with different titles. His title or name "Jorightu Khagan" means "Brave King" in the Mongolian language.

After the murder of Uskhal Khan by Yesüder, the Mongols quickly disintegrated. Gunashiri, a descendant of Chagatai Khan, founded his own small state Qara Del in Hami. Uskhal Khan's former minister, Necelai, submitted to Ming China in 1389 and the Ming established a Mongol guard of Tyuanin (also known as Three Guards) under him in Daiying, modern Inner Mongolia. However, the late khan's chingsang, Shirmen, allied with Yesüder, killed Necelai.

The former prince of Liaodang and one of the leaders of the Three Guards, Ajashir, threw his allegiance to Yesüder some time after 1389. In 1392, the Ming army invaded Mongolia and captured a large number of cattle and men.
