Li Guangyan (李光顏) (761–826), courtesy name Guangyuan (光遠), né Adie Guangyan (阿跌光顏), was a general of the Chinese dynasty Tang Dynasty. He was known for his participation in various campaigns against regional warlords during the reigns of Emperor Xianzong and Emperor Muzong.
Adie Guangyan was born in 761, during the reign of Emperor Suzong. He had at least one older brother, Adie Guangjin (阿跌光進), and one older sister, who was older than Adie Guangjin. Their father Adie Liangchen (阿跌良臣) had been a hereditary prefect of Jitian Prefecture (雞田州) — one of the prefectures that Tang established for the settlement of Huigu-related tribes that submitted to Tang during the reign of Emperor Taizong in the Hequ (河曲, i.e., the Ordos Desert region). — and his tribal army was part of the army of Shuofang Circuit (朔方, headquartered in modern Yinchuan, Ningxia).
Adie Guangyan's older sister married an army officer named Sheli Gezhan (舍利葛旃). In 764, when the military governor (Jiedushi) of Shuofang, Pugu Huai'en, was in rebellion against Emperor Suzong's son Emperor Daizong, Sheli participated in the killing of Pugu's son Pugu Yang (僕固瑒) and subsequently submitted to the imperial general Xin Yunjing (辛雲京), the military governor of Hedong Circuit (河東, headquartered in modern Taiyuan, Shanxi). As the Adie brothers were dependent on their brother-in-law, they also settled their household at Hedong's capital Taiyuan. Both Adie Guangjin and Adie Guangyan learned riding and archery skills from Sheli. It was said that while Adie Guangjin was brave and resolute, his fighting abilities and strategies were not as good as Sheli's, but that Sheli was particularly complimentary of Adie Guangyan, whose abilities he considered superior to his own.
