What is the name of the national anthem?

Why this is the answer

The United States has one official national anthem: "The Star-Spangled Banner." It was inspired by the flag at Fort McHenry and became the official anthem in 1931. Other patriotic songs are well known, but they are not the national anthem.

💡 Memory tip: Remember: "Star-Spangled Banner" means the flag song — the stars and stripes.
