Jani Beg (died 1357) also called Djanibek Khan was a khan of the Golden Horde from 1342 to 1357, succeeding his father Öz Beg Khan.

After putting two of his brothers to death, Jani Beg crowned himself in Saray-Jük. He is known to have actively interfered in the affairs of Russian principalities and of Lithuania. The Grand Princes of Moscow, Simeon Gordiy, and Ivan II, were under constant political and military pressure from Jani Beg.

Jani Beg commanded a massive Crimean Tatar force that attacked the Crimean port city of Kaffa in 1343. The siege was lifted by an Italian relief force in February. In 1345 Jani Beg again besieged Kaffa; however, his assault was again unsuccessful due to an outbreak of the Black Plague among his troops. It is thought that Jani Beg's army catapulted infected corpses into Kaffa in an attempt to use the Black Death to weaken the defenders. Infected Genoese sailors subsequently sailed from Kaffa to Genoa, introducing the Black Death into Europe.

In 1356 Jani Beg conducted a military campaign in Azerbaijan and conquered the city of Tabriz, installing his own governor there. He also asserted Jochid dominance over the Chagatai Khanate, attempting to unite the three khanates of the Mongol Empire. After accepting surrender from Shaikh Uvais, Janibeg boasted that three uluses (districts/nations) of the Mongol Empire were under his control. Soon after this, Jani Beg faced an uprising in Tabriz resulting in the rise to power of the Jalayirid Dynasty, an offshoot of Ilkhanate and, ultimately, in the death of the Khan.
