List of United States Army campaigns during World War II

The United States Army conducted many campaigns during World War II. These are the campaigns that were officially designated by the Army. It is the basis of campaign honors and awards for U.S. Army units and servicemen,^[1][2] but is not a comprehensive list of all the campaigns of the war, as it omits campaigns in which U.S. Army participation was minimal.^[3]

In all, 44 World War II campaigns were designated by the U.S. Army: 24 for the Asiatic–Pacific Theater, 19 in the European–African–Middle Eastern Theater, and one in the American Theater. In addition, there were three main blanket campaigns: antisubmarine warfare, ground combat and air combat. These were designated for each theater, except the American Theater, which only had the one blanket campaign awarded – anti-submarine warfare. These three theaters each had its own campaign ribbon. The list of campaigns includes those undertaken by U.S. Army units participating in ground combat as well as those undertaken by United States Army Air Forces participating in air combat.^[3]
