Luan Ying 欒盈 (died 550 BCE), personal name Ji Ying 姬盈, also called Luan Cheng 欒逞 or Luan Ruzi 欒孺子, posthumous title Luan Huaizi 欒懷子, was a nobleman in the state of Jin 晉 during the Spring and Autumn period 春秋 (770-5th cent. BCE). He was a member of the house of Luan 欒, a grandson of Luan Shu 欒書 and a son of Luan Yan 欒黶 and served Duke Ping of Jin 晉平公 (r. 558-532) as a grand master (dafu 大夫) in the position of assistant commander of the Lower Army (xiajun zuo 下軍佐).
He therefore participated in Duke Ping's campaign against the state of Qi 齊 in 555 BCE. Liang Ying had a personal conflict with Shi Yang 士鞅 (Fan Xianzi 范獻子). Yang's father Shi Gai 士匄 (Fan Xuanzi 范宣子) therefore ordered him to fortify the town of Zhu 著 as a formal condition to force him into exile. Luan Ying first went in the state of Chu 楚, later to Qi.
In 550, he secretly returned to his fief Quwo 曲沃 and, with the support of Wei Shu 魏舒 (Wei Xianzi 魏獻子), built up an army and attacked the capital of Jin in Jiang 絳. His assault failed and he withdrew to Quwo, yet the army of Jin soon took this town, and the house of Luan was annihilated.
