Jalal al-Din Khan ibn Tokhtamysh (Urdu; Persian; Arabic: جلال الدین خان ابن تختامش; Tatar: Cäläletdin, Polish: Dżalal ad-Din) (1380–1412) was the khan of the Golden Horde in 1411–1412. He was the son of Tokhtamysh Khan. He is also famous for his written history of the Mongol Empire. He is also known as the Green Sultan.

After his father Tokhtamysh died in c. 1405, Jalal al-Din Khan ibn Tokhtamysh fled to Lithuania to seek assistance from the Lithuanian Grand Prince Vytautas the Great. In 1410, he took part in the Battle of Grunwald, Tannenberg under Vytautas against the Teutonic Knights. The allies decisively inflicted a crushing defeat on the Military Order.

In the following year, with Lithuanian support, he overthrew Temur Khan ibn Temur Qutlugh of the Golden Horde, and retook the throne of Saray al-Jadid while his other opponent Edigu was in Khorazm. Sometime after 1411 he minted coins with his name. According to a Russian chronicle, Jalal was murdered by his brother Karim Berdi after his brief reign.
