The Battle of Dengbu Island (登步島戰役) 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 November 3, 1949 to November 5, 1949 and resulted in a Republic of China victory. Nevertheless, the ROC was later forced to withdraw when the PRC gained air superiority over the region, leaving Dengbu Island in the control of the PRC.
