Fear is a 1925 novella by the Austrian writer Stefan Zweig. It was adapted into a 1928 silent film Angst directed by Hans Steinhoff a 1936 film La Peur directed by Victor Tourjansky and a 1954 film Fear directed by Roberto Rossellini.

The protagonist Irene Wagner is a married young bourgeois who has a secret affair with a pianist. Due to blackmails from the pianist's girlfriend who is aware of the affair Irene is seized with fear of losing her dolce vita.

Nicholas Lezard of The Guardian reviewed the book in 2010: "This is the stuff of melodrama: the typical Zweigian scenario in which beneath the trappings of respectability storms of carnal passion guilt shame and rage. It is no accident you feel that Zweig was writing at the same time and in the same city as Sigmund Freud."
