Xie Ai (simplified Chinese: 谢艾; traditional Chinese: 謝艾; pinyin: Xiè ài, 301–354) was a general for the Chinese state Former Liang who served under Zhang Chonghua.
Xie Ai was initially regarded as only capable in civilian matters, and apparently served as a civilian official during the rule of Zhang Chonghua's father Zhang Jun. In 346, in light of Zhang Jun's death and succession by Zhang Chonghua, Later Zhao launched a major attack against Former Liang, with intent to destroy Former Liang. Under the recommendation of the general Zhang Chen (張耽), who knew of Xie's capabilities in military strategy, Zhang Chonghua made Xie a general and had him face the Later Zhao forces commanded by Wang Zhuo (王擢) and Ma Qiu (麻秋). After an initial victory later in 346, Zhang Chonghua created Xie the Count of Fulu. In 347, as Ma sieged the important city Fuhan (枹罕, in modern Linxia Hui Autonomous Prefecture, Gansu), Zhang Chonghua sent Xie to try to relieve the city. As Xie arrived at the frontline, he was seen wearing a white cap and riding in a wagon—making him appear to be a civilian—and Ma felt insulted that Xie apparently did not consider his siege an emergency. He sent some elite soldiers to make an attack against Xie, but Xie calmly responded, and Ma's elite soldiers thought they were getting into a trap and stopped their advance. Meanwhile, an army sent by Xie had already gone behind them and started an attack. Xie then advanced as well and dealt Ma a great loss. In the fall, Ma attacked Former Liang again and was again repelled by Xie. (However, Xie's victories appeared to be insufficient for Former Liang to regain the territories lost in the initial Later Zhao attack, south of the Yellow River.)
