The Battle of Guningtou (古寧頭之役), also known as the Battle of Kuningtou or the Battle of Kinmen (Chinese: 金門戰役), was fought in October 1949 on the island of Kinmen (Quemoy), located in the Taiwan Strait, during the final stages of the Chinese Civil War.

The battle resulted in a decisive victory for the Republic of China (ROC, known today as Taiwan) forces and marked a significant turning point in the civil war. The defeat of Chinese Communist Party (CCP) forces not only preserved Kinmen under ROC control but also effectively halted CCP plans for an immediate invasion of Taiwan. The victory ensured the survival of the Republic of China government on Taiwan and reshaped the strategic landscape of the Taiwan Strait.

Starting in 2025, October 25 is designated annually as "Taiwan Retrocession Day and the Anniversary of the Battle of Guningtou" to commemorate victory of the battle along with the Taiwan Retrocession Day, which is a public holiday in Taiwan.
