All Quiet on the Western Front (German: Im Westen nichts Neues, lit. 'Nothing New In the West') is a novel by Erich Maria Remarque, a German veteran of World War I. The book describes the German soldiers' extreme physical and mental stress during the war, and the detachment from civilian life felt by many of these soldiers upon returning home from the front.

The novel was first published in November and December 1928 in the German newspaper Vossische Zeitung and in book form in late January 1929. The book and its sequel, The Road Back (1930), were among the books banned and burned in Nazi Germany. All Quiet on the Western Front sold 2.5 million copies in 22 languages in its first 18 months in print.

In 1930, the book was adapted as an Academy-Award-winning film of the same name, directed by Lewis Milestone. It was adapted again in 1979 by Delbert Mann, this time as a television film starring Richard Thomas and Ernest Borgnine.
