Mist (Spanish: Niebla) is a novel written by Miguel de Unamuno in 1907 and first published in 1914 by Editorial Renacimiento.

[1] The plot revolves around the character of Augusto, a wealthy, intellectual and introverted young man.

He falls in love with a young woman named Eugenia as she walks past him on the street, and he sets about trying to court her.

Her Aunt Ermelinda is particularly keen for a relationship to evolve, so that Augusto might help with her niece's financial troubles.

Augusto asserts that he exists, even though he acknowledges internally that he doesn't, and threatens Unamuno by telling him that he is not the ultimate author.

Augusto describes his world as full of small and almost imperceptible occurrences, some of them good, some of them bad, that all serve to obscure his vision.

Ardila have contended that Mist was inspired by the Danish philosopher Søren Kierkegaard's work Diary of a Seducer, a novella in Either/Or.
