The Bataan Death March (Filipino: Martsa ng Kamatayan sa Bataan; Kapampangan: Martsa ning Kematayan king Bataan; Japanese: , Hepburn: Batn Shi no Kshin) was the forcible transfer by the Imperial Japanese Army of 60,00080,000 American and Filipino prisoners of war from Saysain Point, Bagac, Bataan and Mariveles to Camp O'Donnell, Capas, Tarlac, via San Fernando, Pampanga, the prisoners being forced to march despite many dying on the journey.

The transfer began on April 9, 1942, after the three-month Battle of Bataan in the Philippines during World War II. The total distance marched from Mariveles to San Fernando and from the Capas Train Station to Camp O'Donnell is variously reported by differing sources as between 60 and 69.6 miles (96.6 and 112.0 km). Sources also report widely differing prisoner of war casualties prior to reaching Camp O'Donnell: from 5,000 to 18,000 Filipino deaths and 500 to 650 American deaths during the march.

The march was characterized by severe physical abuse and wanton killings. After the war, the Japanese commander, General Masaharu Homma and two of his officers, Major General Yoshitaka Kawane and Colonel Kurataro Hirano, were tried by United States military commissions for war crimes and sentenced to death on charges of failing to prevent their subordinates from committing war crimes. Homma was executed in 1946, while Kawane and Hirano were executed in 1949.

The Battle of Bataan (Tagalog: Labanan sa Bataan; January 7 – April 9, 1942) was fought by the United States and the Philippine Commonwealth against Japan during World War II. The battle represented the most intense phase of the Japanese invasion of the Philippines during World War II. In January 1942, forces of the Imperial Japanese Army and Navy invaded Luzon along with several islands in the Philippine Archipelago after the bombing of the American naval base at Pearl Harbor.

The commander-in-chief of all U.S. and Filipino forces in the islands, General Douglas MacArthur, consolidated all of his Luzon-based units on the Bataan Peninsula to fight against the Japanese army. By this time, the Japanese controlled nearly all of Southeast Asia. The Bataan Peninsula and the island of Corregidor were the only remaining Allied strongholds in the region.

Despite their lack of supplies, American and Filipino forces managed to fight the Japanese for three months, engaging them initially in a fighting retreat southward. As the combined American and Filipino forces made a last stand, the delay cost the Japanese valuable time and prevented immediate victory across the Pacific. The American surrender at Bataan to the Japanese, with 76,000 soldiers surrendering in the Philippines altogether, was the largest in American and Filipino military histories, and was the largest United States surrender since the American Civil War's Battle of Harpers Ferry. Soon afterwards, U.S. and Filipino prisoners of war were forced into the Bataan Death March.
