Adam Kuckhoff (30 August 1887 in Aachen – 5 August 1943 in Berlin-Plötzensee; executed) was a German writer, journalist, and resistance fighter in the Third Reich.
Adam Kuckhoff published a popular edition of the works of Georg Büchner in 1927, and headed the cultural-political magazine Die Tat ("The Deed") in 1928-1929, which he gave a leftwing democratic flavour. In 1931, he wrote the artistic novel Scherry about Grock. After that, in 1931-1932, he was a dramatic adviser at the Berliner Schauspielhaus. His main work, the world war novel Der Deutsche von Bayencourt ("The German from Bayencourt") appeared in Germany in 1937.
Together with his wife Greta and the married couple Arvid and Mildred Harnack, he conspired to build the resistance group that the Gestapo would later call the Red Orchestra (Rote Kapelle). On 12 September 1942, he was arrested in Prague.
In East Germany, Kuckhoff was honoured as a resistance fighter. In Leipzig-Grünau a school was named after him. It bore his name from 1985 to 1990.
