What is the name of the national anthem of the United States?

The national anthem of the United States is "The Star-Spangled Banner." This song was penned by Francis Scott Key in 1814 and officially adopted as the national anthem in 1931. It was inspired by Key's observations during the bombardment of Fort McHenry in Baltimore Harbor, where he was motivated by the sight of the American flag, or the "star-spangled banner," flying triumphantly after the attack. The anthem's lyrics reflect themes of resilience and patriotism, making it a fitting symbol of the nation’s identity.

The other options, while significant in American music and culture, serve different purposes. "America the Beautiful" is a beloved patriotic song that celebrates the beauty and promise of the United States but is not designated as the national anthem. "This Land is Your Land," written by Woody Guthrie, is an iconic folk song that expresses the spirit of inclusivity and shared ownership of the land but lacks the formal recognition that "The Star-Spangled Banner" holds. "Yankee Doodle," a song that dates back to the American Revolutionary War, has also been associated with patriotism but serves more as a humorous song than as a national anthem.
