Emperor Gong of Jin (simplified Chinese: 晋恭帝; traditional Chinese: 晉恭帝; pinyin: Jìn Gōng Dì; Wade–Giles: Chin Kung-ti; 386–421) was last emperor of the Eastern Jin Dynasty (265-420) in China. He became emperor in 419 after his developmentally disabled brother Emperor An was killed by the regent Liu Yu, and during his brief reign, actual power was in Liu Yu's hands. In 420, under pressure from Liu Yu, he yielded the throne to Liu Yu, ending Jin's existence. Liu Yu founded Liu Song, and in 421, believing that the former Jin emperor posed a threat to his rule, had him asphyxiated with a blanket.

Sima Dewen was born to Emperor Xiaowu of Jin and his concubine Consort Chen Guinü in 386, as their second son, four years after Consort Chen had given birth to their oldest son, Sima Dezong. Contrary to the developmentally disabled Sima Dezong, who was described as even unable to put on clothes himself, feed himself, or be aware whether he was hungry or full, Sima Dewen was described as an intelligent child. From his childhood, he became accustomed to care for his brother, perhaps particularly in light of their mother's death in 390. Their father did not have any other sons. Despite Sima Dezong's developmental disability, however, Emperor Xiaowu appeared to not have considered not making him his heir and making Sima Dewen his heir instead. Indeed, in 387, when Sima Dezong was just five years old and Sima Dewen was just one, he created Sima Dezong crown prince. In 392, Emperor Xiaowu created Sima Dewen the Prince of Langye—the most honored title for a prince after crown prince. In 396, Emperor Xiaowu was strangled by his favorite concubine Consort Zhang, and Sima Dezong became emperor (as Emperor An). Sima Dewen continued to care for his daily living.
