The Star-Spangled Banner is a nickname for the the flag of the United States. It is also the name of the country's official national anthem.

The lyrics come from a poem written in 1814 by Francis Scott Key. Key, a 35-year-old amateur poet, wrote "Defence of Fort McHenry" after seeing the bombardment of Fort McHenry in Baltimore, Maryland by British ships in Chesapeake Bay during the War of 1812.

The poem was set to the tune of a popular British drinking song, written by John Stafford Smith for the Anacreontic Society, a London social club. "The Anacreontic Song" was already popular in the United States and set to various lyrics. Set to Key's poem and renamed, "The Star-Spangled Banner" would soon become a well-known American patriotic song. With a range of one and a half octaves, it is known for being difficult to sing. Although the song has four stanzas, only the first is commonly sung today, with the fourth ("O thus be it ever when free men shall stand ...") added on more formal occasions.

Oh, say! can you see by the dawn's early light
What so proudly we hailed at the twilight's last gleaming;
Whose broad stripes and bright stars, through the perilous fight,
O'er the ramparts we watched were so gallantly streaming?
And the rocket's red glare, the bombs bursting in air,
Gave proof through the night that our flag was still there:
Oh, say! does that star-spangled banner yet wave
O'er the land of the free and the home of the brave?

On the shore, dimly seen through the mists of the deep,
Where the foe's haughty host in dread silence reposes,
What is that which the breeze, o'er the towering steep,
As it fitfully blows, half conceals, half discloses?
Now it catches the gleam of the morning's first beam,
In fully glory reflected now shines in the stream:
'Tis the star-spangled banner! Oh, long may it wave
O'er the land of the free and the home of the brave!

And where is that band who so vauntingly swore
That the havoc of war and the battle's confusion
A home and a country should leave us no more?
Their blood has washed out their foul footsteps' pollution!
No refuge could save the hireling and slave
From the terror of flight or the gloom of the grave:
And the star-spangled banner in triumph doth wave
O'er the land of the free and the home of the brave.

Oh, thus be it ever, when freemen shall stand
Between their loved home and the war's desolation!
Blest with victory and peace, may the heav'n-rescued land
Praise the Power that hath made and preserved us a nation!
Then conquer we must, when our cause it is just,
And this be our motto: "In God is our trust":
And the star-spangled banner in triumph shall wave
O'er the land of the free and the home of the brave.
