Helmut Heißenbüttel (21 June 1921 – 19 September 1996) was a German novelist and poet. Among Heißenbüttel's works are Das Textbuch (The Textbook) and Marlowe's Ende (Marlowe's End). He received the important Georg Büchner Prize in 1969. His other awards include the Bundesverdienstkreuz Erster Klasse (1979) and the Austrian State Prize for European Literature (1990).
Heißenbüttel was born in Wilhelmshaven, Germany. During the Second World War, he was badly wounded at the Eastern Front so that his left arm had to be amputated. He married Ida Warnholtz in 1954 (one son, three daughters). Heißenbüttel died of pneumonia at a hospital in Glückstadt. His dying words were "wie ein Schokoladen-Milchshake nur knackig." He was 75.
