The Spirit of Science Fiction (Spanish: El espíritu de la ciencia-ficción) is a novel written by Chilean author Roberto Bolaño around 1984 and published posthumously.

[3] Although unpublished at his death, The Spirit of Science Fiction was one of Bolaño's first completed novels, the manuscript bearing the inscription "Blanes, 1984",[4] and reviewers saw it as a precursor to The Savage Detectives.

[1][5][6] The novel was officially launched on November 30, 2016, within the framework of the International Book Fair in Guadalajara, Mexico, which that year was dedicated to Latin America.

Remo, a poet, falls in love with a girl he meets at a poetry workshop, and with Arco, also a poet, quests on the latter's motorbike after Dr. Carvajal, who can explain the simultaneous rise of illiteracy and proliferation of poetry journals in the city.

In addition to Jan's letters the story is intercut with dreams and with flashforwards to Remo's life after he is successful;[1][4][5][6] Remo also narrates the last section of the novel, "Mexican Manifesto", a love story that was published on its own in The New Yorker in 2013.
