The Japanese invasion of Burma, referred to by the BIA in 1941 as the fourth Anglo-Burmese war or the war of Burmese Independence, was a series of battles fought in the British colony of Burma (present-day Myanmar) as part of the Pacific theater of World War II. The initial invasion in 1942 resulted in the capture of Rangoon and the retreat of British, Indian, and Chinese forces. The invasion had the support of the Burma Independence Army (BIA), which fought in view of decolonization. However, Japan installed a puppet state in Burma, which lost the support of the Burmese people.

After the invasion, from 1942 to 1945, the Allies and Japan engaged in a protracted struggle for control of the region, marked by fierce fighting in challenging terrain. The Burma campaign was strategically significant, as it was linked to the war in China and the supply routes to the Chinese Nationalists. The eventual Allied victory in 1945 played a crucial role in the overall defeat of Japan.
