Martín Adán, pseudonym of Rafael de la Fuente Benavides, was a Peruvian poet whose body of work is notable for its hermeticism and metaphysical depth.

Martín Adan's first book was the novel La casa de cartón (The Cardboard House). Published in 1928 when the author was only 20 years old, The Cardboard House was influenced by the Avant-garde and is one of the best examples of Peruvian narrative of its time. The novel was told through the paintings of a young man's experiences and reflections and was notable for evoking the district of Lima, Barranco. The Cardboard House's innovative theme and structure can, in some ways, be considered precursorial to novels of the literary boom in Latin America.

The remainder of Adán's work was poetry. It stands out for a profundity of philosophical reflection, that sinks into the mysteries of what is eternal and transcendent. His poetry incorporates a series of images and hermetic, symbolic metaphors (among them, notably, the rose). Adán's poetry mixes novel uses of language with traditional poetic forms like the sonnet. Reality and identity are also common themes in his poetry.

With his body of poetry, Adán tried to achieve a "creación total" (total creation) through "la poesía absoluta" (absolute poetry) and affirm the divine power and omnipotence of the poet who creates realities.
