The Battle of Guningtou, was a battle fought over Kinmen in the Taiwan Strait during the Chinese Civil War in 1949. The failure of the Communists to take the island left it in the hands of the Kuomintang (Nationalists) and crushed their chances of taking Taiwan to destroy the Nationalists completely in the war.

For ROC forces accustomed to continuous defeats against the PLA on the mainland, the victory at Guningtou provided a much-needed morale boost. The failure of the PRC to take Kinmen effectively halted its advance towards Taiwan. With the outbreak of the Korean War in 1950 and the signing of the Sino-American Mutual Defense Treaty in 1954, the Communist plans to invade Taiwan were put on hold.
