Uskhal Khan, born Tögüs Temür (r. 1378-1388), was the Mongol Khan of the Northern Yuan Dynasty in Mongolia. He used the era name Tianyuan (天元).

Tögüs Temür was Biligtü Khan's younger brother and son of Toghan Temur, the last effective Great Khan of the Mongols. He succeeded to the throne after Biligtü Khan died in 1378. He continued to press the Ming from the north, cooperating with Naghachu of the Jalayir in Manchuria. However, he suddenly faced a predicament in 1387 when Nagachu surrendered to the Ming due to a devastating famine. In 1388 he was raided by the Ming on the Buyir Nuur. In his escape to Karakorum, he was killed on the Tuul River by Yesüder, a descendant of Ariq Boke, who allied with the Oirats.^[1] This marked the fall of the Kublaid power and the rise of the Oirats in Mongolia.
