Liu Peng (Chinese: 劉怦; 727 – November 4, 785[1][2]), formally Duke Gong of Pengcheng (彭城恭公), was a general of the Chinese Tang dynasty, who served as military governor (Jiedushi)[3] of Lulong Circuit (盧龍, headquartered in modern Beijing) briefly in 785 following the death of his cousin, the warlord Zhu Tao.
^According to Liu Peng's biographies in the Old Book of Tang and the New Book of Tang, Liu Peng was made deputy military governor with the title Fudashi (副大使).

However, the chronicles of Emperor Dezong's reign in the Old Book of Tang and the New Book of Tang both indicated that Liu was made military governor, and this was followed by the Zizhi Tongjian. See Old Book of Tang, vol. 12 (which, however, also referred to him as deputy military governor), New Book of Tang, vol. 7Archived 2007-12-26 at the Wayback Machine, and Zizhi Tongjian, vol. 232. As the Fudashi title would also indicate that he was acting as governor but titularly serving as a deputy to an imperial prince — one of Emperor Dezong's brothers or sons — but none of Emperor Dezong's brothers or sons carried the title of military governor of Zhenwu, it would appear that he was made military governor.
