Jayaatu Khan Tugh Temür, Chinese emperor (d. 1332)
Jayaatu Khan (Chinese: 札牙篤汗; Mongolian: Заяат хаан, Jayaγatu qaγan), born Tugh Temür, also known by the temple name Wenzong (Emperor Wenzong of Yuan, Chinese: 元文宗; 16 February 1304 – 2 September 1332), was an emperor of the Yuan dynasty of China. Apart from Emperor of China, he is regarded as the 12th Great Khan of the Mongol Empire, although it was only nominal due to the division of the empire.

He first ruled from 16 October 1328 to 3 April 1329 before abdicating in favour of his brother Khutughtu Khan Kusala, and again ruled from 8 September 1329 to 2 September 1332 after Khutughtu Khan Kusala's death.

Thanks to his father's loyal partisans, Tugh Temür did restore the line of Khayishan to the throne; but persecuted his eldest brother Kusala's family, and later expressed remorse for what he had done to him. His name means "Blessed/lucky Khan" in the Mongolian language.

Tugh Temür sponsored many cultural activities, wrote poetry, painted, and read Chinese classical texts. Examples of his quite competent poetry and calligraphy have survived. He mandated and closely monitored the compilation called "The Imperial Dynasty's grand institutions for managing the world"; through this textual production, he proclaimed his reign as new beginning, which took stock of the administrative practices and rules of the past and looked forward to a fresh chapter in Yuan dynastic governance. But his reign was brief, and his administration was in the hands of powerful ministers, such as El Temür of the Qipchaq and Bayan of the Merkid who had helped him to win the succession struggle in 1328.
