The Pantingan River massacre (Filipino: Pagpatay sa Ilog Pantingan) was the mass execution of Filipino and American officers and non-commissioned officers Prisoners-of-War by members of the Imperial Japanese Army during the Bataan Death March on April 12, 1942, in Bagac, Bataan.

[2] Several hundred soldiers from the Philippine Commonwealth Army's 1st, 11th, 71st, and 91st Divisions on the march to the north of Mount Samat where the Pantingan River crosses the Pilar-Bagac Road were taken to the riverside.

Most of them were hog tied with telephone wire, shot, bayoneted or beheaded by the Imperial Japanese Army.

[4] Following Tsuji's abnormal order, which was considered to be a war crime and beyond his commission, the Japanese 122nd Regiment of 65th Brigade executed the US and Philippine soldiers in the Pantingan River.

[6][7][8] Survivors of the massacre include Lt. Manuel Yan who later became the head of the Armed Forces of the Philippines and ambassador to Thailand.
