Yong Kai (died 225) was the prefect of Jianning Commandery in the state of Shu Han during the Three Kingdoms period of Chinese history. He joined the Nanman chieftain Meng Huo in revolting against Shu Han. During the Shu Han chancellor Zhuge Liang led a southern campaign to suppress the rebellion, he used a strategy to turn Yong and another rebel leader, Gao Ding, against each other. Yong was killed by Gao's servant He Huang, and the rebellion effectively ended.
