The Battle of Imphal took place in the region around the city of Imphal, the capital of the state of Manipur in Northeast India from March until July 1944. Japanese armies attempted to destroy the Allied forces at Imphal and invade India, but were driven back into Burma with heavy losses. Together with the simultaneous Battle of Kohima on the road by which the encircled Allied forces at Imphal were relieved, the battle was the turning point of the Burma campaign, part of the South-East Asian theatre of World War II. The Japanese defeat at Kohima and Imphal was the largest up until that time, with many of the Japanese deaths resulting from starvation, disease and exhaustion suffered during their retreat. According to voting in a contest run by the British National Army Museum, the Battle of Imphal was bestowed as Britain's Greatest Battle in 2013.

Imphal is the capital city of the Indian state of Manipur. It is the fourth largest city in northeast India after Aizawl.
