Named after the avenue Philippe-Auguste, which honours King Philip II Augustus (reigned 1180–1223).
It is the only metro station named after a king of France. The monk Rigord called Philip 'Auguste' because he had enlarged the royal domain and was born in August. He had Paris walled and the château du Louvre built. The avenue was named in 1864; his statue stands on a column of the barrière du Trône.
