Li Kuangwei (李匡威) (d. 893) was a warlord late in the Chinese dynasty Tang Dynasty, who controlled Lulong Circuit (盧龍, headquartered in modern Beijing) after inherited it from his father Li Quanzhong in 886, until he was overthrown by his brother Li Kuangchou in 893. After he was overthrown, he resided briefly at the domain of his ally Wang Rong the military governor of Chengde Circuit (成德, headquartered in modern Shijiazhuang, Hebei). He subsequently tried to seize control of the circuit from Wang, but was killed by Chengde soldiers faithful to Wang.
It is not known when Li Kuangwei was born, but it is known that his family was from Lulong Circuit's capital Fanyang. The first historical reference to him was in 886, when his father, the military governor (Jiedushi) Li Quanzhong, who had seized control of Lulong in 885 after overthrowing the prior military governor Li Keju, died, and Li Kuangwei thereafter claimed the title of acting military governor. At some point, the imperial government confirmed him as full military governor.
It was said that Li Kuangwei was ambitious, and, because the Tang state was in disarray at the time, he strengthened his army with the intent of eventually trying to occupy more territory.
In 890, another major warlord, Li Keyong the military governor of Hedong Circuit (河東, headquartered in modern Taiyuan, Shanxi), attacked Helian Duo the defender of Yun Prefecture (雲州, in modern Datong, Shanxi), capturing its eastern part. Helian sought aid from Li Kuangwei, and Li Kuangwei took 30,000 men to aid him. After Li Keyong's officer An Jinjun (安金俊) died in battle and another officer, Shen Xin (申信), surrendered to Helian, Li Keyong was forced to withdraw.
