The National Revolutionary Army (NRA), sometimes shortened to Revolutionary Army (革命軍) before 1928, and as National Army (國軍) after 1928, was the military arm of the Kuomintang (KMT, or the Chinese Nationalist Party) from 1925 until 1947 in the Republic of China. It also became the regular army of the ROC during the KMT's period of party rule beginning in 1928. It was renamed the Republic of China Armed Forces after the 1947 Constitution, which instituted civilian control of the military.

Originally organized with Soviet aid as a means for the KMT to unify China during the Warlord Era, the National Revolutionary Army fought major engagements in the Northern Expedition against the Chinese Beiyang Army warlords, in the Second Sino-Japanese War (1937-1945) against the Imperial Japanese Army and in the Chinese Civil War against the People's Liberation Army.

During the Second Sino-Japanese War, the armed forces of the Communist Party of China were nominally incorporated into the National Revolutionary Army (while retaining separate commands), but broke away to form the People's Liberation Army shortly after the end of the war. With the promulgation of the Constitution of the Republic of China in 1947 and the formal end of the KMT party-state, the National Revolutionary Army was renamed the Republic of China Armed Forces, with the bulk of its forces forming the Republic of China Army, which retreated to the island of Taiwan in 1949.
