Text: The ''Argentine National Anthem'' (Spanish: Himno Nacional Argentino) is the national anthem of Argentina. Its lyrics were written by the Buenos Aires-born politician Vicente Lopez y Planes and the music was composed by the Spanish musician Blas Parera. The work was adopted as the sole official song on May 11, 1813, three years after the May Revolution; May 11 is therefore now Anthem Day in Argentina.
