Andrei Platonov, August 28, 1899 – January 5, 1951, was the pen name of Andrei Platonovich Klimentov, a Soviet author whose works anticipate existentialism. Although Platonov was a Communist, his works were banned in his own lifetime for their skeptical attitude toward collectivization and other Stalinist policies.

From 1918 through 1921, his most intensive period as a writer, he published dozens of poems (an anthology appeared in 1922), several stories, and hundreds of articles and essays, adopting in 1920 the Platonov pen-name by which he is best-known. With remarkably high energy and intellectual precocity he wrote confidently across a wide range of topics including literature, art, cultural life, science, philosophy, religion, education, politics, the civil war, foreign relations, economics, technology, famine, and land reclamation, amongst others.

His famous works include the novels The Foundation Pit and Chevengur.
