Flanders Field American Cemetery and Memorial is a World War I cemetery in the city of Waregem, Belgium. Originally a temporary battlefield burial ground, Flanders Field American Cemetery later became the only permanent American World War I cemetery in Belgium.  The Flanders Field American Cemetery commemorates 411 service members of the United States Armed Forces of which 368 are interred. The Walls of the Missing inside the chapel venerates 43 missing service members.

This cemetery is administered by the American Battle Monuments Commission (ABMC) and occupies a six-acre (about 2.6 hectares) site.  The government of Belgium granted its free use as a permanent burial ground in perpetuity without charge or taxation.

At the center of the cemetery is the small memorial chapel of white Pouillenay stone. Above its bronze entrance door is engraved:

This Chapel Has Been Erected By The United States Of America In Memory Of Her Soldiers Who Fought And Died In Belgium During The World War. These Graves Are The Permanent And Visible Symbol Of The Heroic Devotion With Which They Gave Their Lives To The Common Cause Of Humanity

Beneath the three versions of the inscription, sculptured bas-relief figures symbolizing Grief, Remembrance, and History respectively appear.

Located inside the chapel is an altar of Grand Antique (black and white) marble.  On the front of the altar is inscribed:
