An Chonghui (d. June 25, 931?) (, fl. 10th century) was the chief of staff (Shumishi) and chief advisor to Li Siyuan (Emperor Mingzong) (r. 926–933) of the Chinese Five Dynasties and Ten Kingdoms period state Later Tang. For most of Emperor Mingzong's reign, An was the most powerful figure at court, making key military and political decisions that, in his eyes, sought to strengthen the authority of the Later Tang imperial state. However, his ruthless actions toward political enemies—including Emperor Mingzong's adoptive son Li Congke the Prince of Lu—created much resentment. After the campaign against the regional warlords Meng Zhixiang and Dong Zhang, which An instigated, stalled, An was forced to retire, and then was killed in retirement, under accusations that he had alienated Meng, Dong, and the Later Tang nominal vassal Qian Liu the King of Wuyue, from the Later Tang emperor.

An Fuqian was subsequently killed in battle when fighting the Xuanwu forces. During Li Cunxu's reign The first historical reference made to An Chonghui himself was in 916, by which time Tang had ended, and the sons of Li Keyong and Zhu Quanzhong were ruling separate and rival realms that they inherited from their fathers—Li Keyong's biological son Li Cunxu as the
