Apostrof (Romanian for "Apostrophe") is a monthly literary magazine published in Cluj-Napoca, Romania under the Romanian Writers' Union patronage. It was founded in 1990 by Babeș-Bolyai University professor Marta Petreu, who is also its editor in chief and main columnist. Among its regular contributors are literary critics Irina Petraș, Ștefan Borbély, and Florin Manolescu.
Apostrof is especially noted for publishing dossiers on 20th century Transylvanian intellectuals, many of whom were subject to censorship by the communist authorities, and for detailing their contribution to Romanian literature. It also publishes regular book chronicles.
