The Chinese Expeditionary Force was an expeditionary unit of China's National Revolutionary Army that was dispatched to Burma and India in support of the Allied efforts against the Imperial Japanese Army during the Japanese invasion and occupation of Burma in the South-East Asian theatre of the Second World War.

The National Revolutionary Army, 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 from 1925 until 1947 in China. It also became the regular army of the Republican era 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.
