The Battle of Dengbu Island () was a conflict between the Republic of China Army and People's Liberation Army over Dengbu Island (in the Zhoushan Islands) near mainland China. This conflict occurred from 3 November 1949 to 5 November 1949 and resulted in a Republic of China Army's victory.
Nevertheless, the Kuomintang was forced to withdraw in May 1950 when the PLA gained air superiority over the region, leaving Dengbu Island in the control of the mainland government.
