Trilce (Lima, 1922) is the best-known book by the Peruvian poet César Vallejo, and is considered, thanks to its lexicographical and syntactical boldness, as a major work of international modernism and a poetic masterpiece of the avant-garde in Spanish.

It consisted of 121 pages of text and 16 of prologue, the latter written by Antenor Orrego, fraternal friend of Vallejo.

On the cover is a pencil portrait of the poet by Victor Morey Peña.

Publication cost Vallejo 150 soles, which he funded from his winnings in a literary contest held in Lima by the cultural society "Entre nous" in December 1921 (the winning story was Beyond Life and Death, which would later form part of his book of stories Escalas melografiadas).
