Eusebio Lillo Robles (born Santiago, Chile August 14, 1826; died July 8, 1910) was a poet, journalist and politician.

Lillo studied in the General José Miguel Carrera National Institute and was one of the many pupils of Andrés Bello.

That same year, he won an award from the "Sociedad Literaria" for his "Canto al dieciocho de septiembre" (Song of September 18).

In 1847 the Minister of Interior and Foreign Affairs, Manuel Camilo Vial, commissioned him to write the lyrics of the Chilean national anthem.

As a result, he was sent to jail and condemned to death during the government of Manuel Montt, but, as he was the writer of the lyrics of the National Anthem, the sentence was changed to exile, and he was sent to the southern city of Valdivia, from which he fled to Lima.
