Western Tai'an Campaign was a series of battles fought between the nationalists and the communists during Chinese Civil War in the post World War II era, and resulted in the communist victory. The communists viewed this campaign as the prelude to Huaihai Campaign.

Although the military action ceased on January 9, 1948, the communist onslaught did not stop. Riding on their military victory, communists immediately launched another round of propaganda, political and psychological offensive aimed to encourage nationalist soldiers to desert or defect. By the end of early spring, nationalist reception centers in regions Mao's Shop and Luan's Bay in the fourth district and in the regions of Confucian Hamlet and Xiaozhi in the fifth district had been completed to support this effort. The Social Affairs Department, the communist spy agency and predecessor of the present day United Front Work Department of the CPC (UFWDCPC), was also reestablished first at Pingyin county for the same purpose. The effort proved to be very successful that by June 15, 1948, 1,873 nationalist draftees from the 190 hamlets of Pingyin county defected to the communist side, or half of total conscripts nationalist army drafted from the local region, bringing back 119 rifles and 26 handguns with them, and this only included the defectors, while nationalist deserters were not included. The biggest communist gain from this propaganda, political and psychological offensive, however, was important intelligence defectors had, and the intelligence obtained had helped the communists in the following Huaihai Campaign to achieve their next victory.
