Xie Hui 謝晦 (390-426), courtesy name Xuanming 宣明, from Yangxia 陽夏, from the commandery of Chenjun 陳郡, was a high minister of the Liu-Song dynasty 劉宋 (420-479), one of the Southern Dynasties 南朝 (420-589).
He was a grandson of Xie Lang 謝朗, an eminent person of the Eastern Jin dynasty 東晉 (317-420). Xie Hui was well educated and served General Meng Chang 孟昶 (d. 410) as a vice general (canjun 參軍). Liu Muzhi 劉穆之 (360-417) recommended him to General Liu Yu 劉裕 (the eventual Emperor Wu Emperor Wu 宋武帝, r. 420-422), who made him recorder (zhubu 主簿) of the Defender-in-Chief (taiwei 太尉), but because of differences with Liu Muzhi, his career halted. After the latter's death, Xie was promoted to gentleman of attendance (congshi zhonglang 從事中郎) and remained in the service of Liu Yu.
When Liu founded the Song dynasty, he invested Xie Hui as District Duke of Wuchang 武昌縣公 and made him head of the palace guard (zongtong suwei 總統宿衛). Liu Yu (Emperor Wu) made Xie Hui one of the regents assisting the underage-emperor Heir Apparent Liu Yifu 劉義符 (the Infant Emperor 宋少帝, r. 422-424). The other regents were Xu Xianzhi 徐羨之 (364-426) and Fu Liang 傅亮 (374-426). Both finally conspired and dethroned Liu Yifu and made his younger brother Liu Yilong 劉義隆 ruler (Emperor Wen 文皇帝, r. 424-453).
Xie Hui was later regional inspector (cishi 刺史) of the province of Jingzhou 荊州 and invested as Commandery Duke of Jianping 建平郡公. In 426, Xu Xianzhi was executed for insubordination towards the Infant Emperor. General Tan Daoji 檀道濟 (394-436) was ordered to attack Xie Hui in central China. Xie's army was defeated, and he died.
