Ernst Herbeck (9 October 1920, Stockerau, Lower Austria – 11 September 1991) was an Austrian poet.
In 1940, at the age of 20, Herbeck was committed to the national mental hospital in Lower Austria (Niederösterreich) where he spent almost his entire life, writing thousands of poems, until his death on 11 September 1991.
Herbeck grew up in Stockerau, Lower Austria, where at the age of 20 whilst working as an unskilled worker in a munitions factory, began displaying signs of schizophrenia.
Two years before his death Herbeck gave over 1,000 of his handwritten sheets to the Austrian national library as donation.
Herbeck also featured as a character in Philipp Weiss's 2013 play Ein schöner Hase ist meistens der Einzellne.
