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

The national anthem of the United States is titled "The Star-Spangled Banner." This piece was written by Francis Scott Key in 1814 and served as a reflection of his experiences during the War of 1812, particularly the defense of Fort McHenry. Its lyrics express the resilience and patriotic spirit of the American people, symbolized by the sight of the American flag still flying after a night of bombardment.

The other options, while significant in American music and culture, are not the national anthem. "Amazing Grace" is a famous hymn with no direct connection to national pride or identity as the anthem represents. "This Land Is Your Land" is a folk song that celebrates the beauty of America but is not officially recognized as the national anthem. Similarly, "America the Beautiful" evokes themes of love for the country but lacks the official status that "The Star-Spangled Banner" holds. Understanding the distinction of the national anthem emphasizes the importance of national symbols and their roles in American culture.
