Yan Liben (Chinese: 閻立本; pinyin: Yán Lìběn; Wade–Giles: Yen Li-pen) (c. 600-673), formally Baron Wenzhen of Boling (博陵文貞男), was a Chinese painter and government official of the early Tang Dynasty. His most renowned work is the Thirteen Emperors Scroll. He also painted the Portraits at Lingyan Pavilion, under Emperor Taizong of Tang, commissioned in 643 to commemorate 24 of the greatest contributors to Emperor Taizong's reign, as well as 18 portraits commemorating the 18 great scholars who served Emperor Taizong when he was the Prince of Qin. Yan's paintings included painted portraits of various Chinese emperors from the Han Dynasty (202 BC-220 AD) up until the Sui Dynasty (581-618) period. His works were highly regarded by the Tang writers Zhu Jingxuan and Zhang Yanyuan, who noted his paintings were "works among the glories of all times".
From the years 669 to 673, Yan Liben also served as a chancellor under Emperor Taizong's son Emperor Gaozong (r. 649-683).
It is not known when Yan Liben was born. His ancestors were originally from Mayi (馬邑, in modern Shuozhou, Shanxi), but had relocated to the Guanzhong region (i.e., the region around Chang'an) several generations prior to Yan Liben. Yan Liben's father Yan Pi (閻毘) was the deputy director of palace affairs during Sui Dynasty, and both Yan Liben and his older brother Yan Lide (閻立德) were known for their abilities in architectural matters and service to the imperial government in that area.
