The Marines' hymn is the official hymn of the United States Marine Corps. It is often also referred to as "The Marine Corps' Hymn". It is the oldest official song in the U.S. Armed Forces. The song has an obscure origin—the words date from the 19th century, but no one knows the author. The music is from the opera Genevieve de Brabant by Jacques Offenbach, which had its début in Paris in 1859. The Marine Corps secured a copyright on the song on August 19, 1919, but it is now in the public domain.

The initial verse is "From the Halls of Montezuma to the Shores of Tripoli". The Tripoli reference is an allusion to the First Barbary War when on April 27, 1805 U.S. Marines and Berbers attacked the Tripolitan city of Derna. This event also also inspired the film The Lion and the Wind.

Lyrics

From the halls of Montezuma, to the shores of Tripoli,
We fight our country's battles in the air, on land and sea.
First to fight for right and freedom, and to keep our honor clean;
We are proud to claim the title of United States Marine.

Our Flag's unfurled to every breeze from dawn to setting sun.
We have fought in every clime and place, where we could take a gun.
In the snow of far off northern lands and in sunny tropic scenes,
You will find us always on the job, the United States Marines.

Here's health to you and to our Corps, which we are proud to serve.
In many a strife we've fought for life and never lost our nerve.
If the Army and the Navy ever look on heaven's scenes,
they will find the streets are guarded by United States Marines.
