The Battle of Shuangduiji was a major campaign fought between the nationalists and the communists during the Chinese Civil War in the post-World War II era, resulting in a communist victory. The campaign was part of the Huaihai campaign.

The communist victory of the Shuangduiji campaign further ensured their victory in the Huaihai campaign, and the victory at Shuangdui Village resulted in killing more than 46,000 nationalists and capturing over 50,000, including Huang Wei, the commanding general officer of the nationalist 12th Army. A huge quantity of hardware was also captured by the communists, including 870 pieces of artillery, 15 tanks, and over 300 motor vehicles, and large amounts of munitions, all of which were immediately used against their former nationalist owners. The communists suffered 36,000 casualties, with the 4th Column of the Central China Field Army suffering the most casualties: 6,827 wounded and 1,853 killed.

This campaign was very significant for the Chinese communists, particularly the communist Central China Field Army which faced absolute technical inferiority due to the lack of artillery and other heavy weapons. The communist victory in the Shuangduiji campaign not only annihilated a significant portion of nationalist troops deployed in the Huaihai campaign, thus ensuring final victory, but also provided the communist Central China Field Army with much needed heavy weapons.
