Juan Ramón Jiménez Mantecón (23 December 1881 – 29 May 1958) was a renowned Spanish poet. He was a prolific writer and received the 1956 Nobel Prize in Literature for his lyrical poetry, which in the Spanish language constitutes an example of high spirit and artistic purity.

Jiménez was an advocate for "pure poetry," a concept that became one of his most important contributions to modern poetry. Among his notable works is Platero y yo (1914), which remains his most famous work. His influence on Spanish verse is marked by the introduction of modernism, a movement that significantly shaped the poetry of his time.
