The National Revolutionary Army (NRA) (), pre-1928 sometimes shortened to or Revolutionary Army and between 1928 and 1947 as or National Army was the Military Arm of the Kuomintang (KMT) from 1925 until 1947, as well as the national army of the Republic of China during the KMT's period of party rule beginning in 1928.

Originally organized with Soviet aid as a means for the KMT to unify China against warlordism, the National Revolutionary Army fought major engagements in the Northern Expedition against the Chinese Beiyang Army warlords, in the Second Sino-Japanese War 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 Taiwan in 1949.

The military was formed through bloody and inhumane forced conscription campaigns; these campaigns are described by Rudolph Rummel as thus:

""Then there was the process of conscription. This was a deadly affair in which men were kidnapped for the army, rounded up indiscriminately by press-gangs or army units among those on the roads or in the towns and villages, or otherwise gathered together. Many men, some the very young and old, were killed resisting or trying to escape. Once collected, they would be roped or chained together and marched, with little food or water, long distances to camp. They often died or were killed along the way, sometimes less than 50 percent reaching camp alive. Then recruit camp was no better, with hospitals resembling Nazi concentration camps like Buchenwald. Probably 3,081,000 died during the Sino-Japanese War; likely another 1,131,000 during the Civil War – 4,212,000 dead in total. Just during conscription.""
