The Asiatic-Pacific theater was the theater of operations of U.S. forces during World War II in and around the Pacific Ocean. From mid-1942 until the end of the war in 1945, there were two U.S. operational commands in the Pacific. The Pacific Ocean Areas (POA), divided into the Central Pacific Area, the North Pacific Area and the South Pacific Area,Template:Sfn were commanded by Fleet Admiral Chester W. Nimitz, Commander-in-Chief Pacific Ocean Areas. The South West Pacific Area (SWPA) was commanded by General of the Army Douglas MacArthur, Supreme Allied Commander South West Pacific Area. During 1945, the United States added the United States Strategic Air Forces in the Pacific, commanded by General Carl A. Spaatz.

Because of the complementary roles of the United States Army and the United States Navy in conducting war, the Pacific Theater had no single Allied or U.S. commander (comparable to General of the Army Dwight D. Eisenhower in the European Theater of Operations). No actual command existed; rather, the Asiatic-Pacific Theater was divided into SWPA, POA, and other forces and theaters, such as the China Burma India Theater.
