Erzhu Tianguang (simplified Chinese: 尔朱天光; traditional Chinese: 爾朱天光; pinyin: Ěrzhū Tiānguāng) (496–532) was a general of the Chinese/Xianbei dynasty Northern Wei. He became a major general during the reign of Emperor Xiaozhuang, when his father's cousin Erzhu Rong was the paramount general of the state. He was renowned for pacifying the Guanzhong region, which had been seized by agrarian rebel generals Moqi Chounu (万俟醜奴) and Wang Qingyun (王慶雲) in 530. He thereafter tried to maintain a relatively distant profile from the other Erzhu clan members, particularly after Emperor Xiaozhuang killed Erzhu Rong later in 530 and then was overthrown and killed by Erzhu Rong's nephew Erzhu Zhao and cousin Erzhu Shilong. In 532, after the other Erzhus had suffered defeats at the hand of the rebelling general Gao Huan, Erzhu Tianguang tried to come to their aid, but was also defeated by another general who rebelled, Husi Chun, and Gao executed him.
