The First Division Monument is located in President's Park, south of State Place Northwest, between 17th Street Northwest and West Executive Avenue Northwest in Washington, DC, United States. The Monument commemorates those who died while serving in the 1st Infantry Division of the U.S. Army of World War I and subsequent wars.

The First Division Monument sits on a plaza in President's Park, west of the White House and south of the Eisenhower Executive Office Building (EEOB) at the corner of 17th Street and State Place, NW. (The EEOB was originally known as the State, War, and Navy Building and then as the Old Executive Office Building.)

The monument was conceived by the Society of the First Division, the veterans' organization of the U.S. Army's First Division (later renamed the 1st Infantry Division), to honor the valiant efforts of the soldiers who fought in World War I. It was dedicated October 4, 1924 and is inscribed with the names of 5,516 fallen servicemen.

The monument was built using Milford pink granite.

Later additions to the monument commemorate the lives of 1st Infantry Division soldiers who died in subsequent wars. The World War II addition on the west side was dedicated in 1957 (4,325 names), the Vietnam War addition on the east side in 1977 (3,079 names), and the Desert Storm plaque in 1995 (27 names).

The #1 red annuals flowerbed (bed length 181 ft) in front of the monument was added as part of First Lady Lady Bird Johnson’s beautification plans in 1965.

Congressional approval was obtained to erect the First Division Monument and its later additions on federal ground.

Department of the Army Policy requires an official campaign to end before names of soldiers killed in that campaign may be added to the monument. The Commanding General, 1st Infantry Division has approved the criteria for determining names and units the Society may add to the First Division Monument. There are 631 names, along with their units to be added, with each name listed under the unit they served at the time.
