Meng Da (; died c. March 228[1]), courtesy name Zidu, was a military general of the state of Cao Wei during the early Three Kingdoms period of China. He previously served the warlords Liu Zhang and Liu Bei during the late Eastern Han dynasty before defecting to Wei. In Wei, he served under the first two rulers, Cao Pi and Cao Rui. Around late 227, he started a rebellion in Wei and aimed to rejoin the Shu-Han but the revolt was swiftly suppressed by the Wei general Sima Yi. Meng Da was captured and executed for treason.
