Lira dos Vinte Anos (in English: Twenty-year-old Lyre) is a poetry anthology written by Brazilian Romantic author Álvares de Azevedo. Originally part of a project that would be written in partnership with Aureliano Lessa and Bernardo Guimarães called As Três Liras (English: The Three Lyres), it was published in 1853. It is one of the few works whose publication was prepared by Álvares himself, due to his premature death on April 25, 1852. From its initial publication in 1853, it would suffer many re-edits, getting to its current form in 1942.
