Philippine Division, or from 1944–45 the 12th Infantry Division, was the core U.S. infantry division of the United States Army's Philippine Department during World War II. On 31 July 1941, the division consisted of 10,473 troops, mostly enlisted Filipinos, known as the Philippine Scouts who formed the 45th and 57th US Infantry Regiments. All of the division's enlisted men, with the exception of the 31st Infantry Regiment, and various military police and headquarters troops, were Philippine Scouts. 
In October 1941, as part of the U.S. Army Forces Far East, plans were made to "triangularize" the division. The 34th Infantry was detached from the 8th Infantry Division and moved to a port of embarkation in December 1941, along with two battalions of 105mm field artillery. The Philippine Division was to have two complete U.S. regimental combat teams in place by January 1942 to provide General Douglas MacArthur with a modern, trained mobile reaction force, while freeing up Philippine Scouts for rounding out other units. The outbreak of war in December 1941, however, isolated the Philippines and prevented implementation of the plan. It was briefly reconstituted as the 12th Infantry Division in 1944–45.

- Units of the Philippine Division were on security missions at Manila, Fort William McKinley, and Bataan prior to the declaration of war in the Pacific, 8 December 1941. After undergoing 2 days of bombings, the Division moved into the field to cover the withdrawal of troops to Bataan and to resist the enemy in the Subic Bay area. From 11 December 1941 to 23 December 1941, positions were organized and strengthened and on 23 December 1941 the Division was assigned to the Bataan Defense Forces. While the 31st Infantry Regiment moved to the vicinity of Zig Zag Pass to cover the flanks of troops withdrawing from central and southern Luzon, 30 December 1941, the rest of the Division organized the main and reserve positions on Bataan. The 31st Infantry Regiment moved to a defensive position on the west side of the Olongapo Road near Layac Junction, 5 January 1942. This junction was lost on 6 January 1942, but the withdrawal to Bataan had been successfully concluded.
- The Division was placed in reserve from 7 January 1942 to 14 January 1942. This period was largely one of reconnaissance and development by the Japanese in preparation for their attack on the main battle position on the Abucay line. Elements repulsed night attacks near Abucay on 10 January 1942 – 12 January 1942, and other elements of the Division counterattacked on the 16 January 1942. Strong offensive and defensive action was not able to prevent enemy penetrations and the Division withdrew to the Reserve Battle Position in the Pilar – Bagac area, 2 February 1942. Until the latter part of March the enemy, made cautious by heavy losses, engaged in patrols and limited local attacks, and after a general retirement, 24 March 1942, did not undertake any serious activity on this front until 28 March 1942. During this period elements of the Division were shifted to assist in the defense of other sectors. The enemy attack on 28 March struck at a division weakened by malnutrition, sickness, and prolonged exposure to combat. The Division, no longer operating as a coordinated unit, was unable to counterattack against heavy enemy assaults.
- On 8 April 1942, the 57th Infantry Regiment and the 31st Infantry Regiment were lost near the Alangan River, and the 45th Infantry Regiment surrendered, 10 April 1942.
- The victory over Japan ended the misery of Japanese prison camps for the survivors of the Philippine Division.
- The Division was briefly reconstituted as the 12th Infantry Division in 1944–45 as the US & Filipino army liberated the Philippines, but was disbanded after the war. However, prior to being disbanded some subordinate units were tasked with Occupation duties on Saipan, Okinawa, and elsewhere. Furthermore, members of the 1st and 2nd Filipino Infantry Regiments who wished to remain in the Philippines upon being discharged were transferred to a subordinate unit under this division.

The regimental colors of the 12th Quartermaster Regiment (PS) were given to an Army nurse (one of the "Angels of Bataan and Corregidor") by the regimental commander. Upon her capture she told the Japanese that they were "only a shawl" and kept them safe throughout more than three years of captivity. Today, the colors are on display at the U.S. Army Quartermaster Museum, Fort Lee, Virginia.
