Ernst Kreuder (29 August 1903 – 24 December 1972) was a German author. He was born in Zeitz and died in Darmstadt.
His 1946 work The Attic Pretenders concerned a secret associations view of imagination and reality and was well received. Unica Zürn considered it to be one of her favorite books. He also wrote works like Those Who Cannot Be Found and The Undiscoverables. Although his works have been described as melancholy or Kafkaesque he stated that "the literary fashion of hopeless despair must be overcome."
