Alexandru Mironescu (July 23, 1903–January 20, 1973) was a Romanian prose writer.
Born in Tecuci, his parents were Victor Mironescu and his wife Elena.
After attending Dimitrie Cantemir High School in Bucharest, he obtained degrees in chemistry and philosophy from the University of Bucharest.
He later obtained a doctorate in science from the Sorbonne and one in philosophy at Bucharest.
From 1929, he was a lecturer at the latter university and a teacher at Saint Sava National College.
He was editor at Semnalul newspaper.
Mironescu's first journalistic contribution appeared in Credin?a newspaper in 1935; exploring both domestic and foreign affairs, he neither commented on daily events as such, nor held firm to a particular ideology, but took the stance of an independent observer, condemning the intellectual elites' isolation with regard to the national, socioeconomic and cultural interest.Mironescu's first book was the 1937 novel Oamenii nimanui.
His work appeared in Evenimentul zilei, Fapta, Familia, Azi, ?ara noastra, Vremea and Revista Funda?iilor Regale.
He also wrote the novel Destramare (1939), the unpublished play Joc în umbra and a few philosophical works.
He stopped publishing after the advent of the Communist regime, and in 1958, together with his son, was arrested for his clandestine religious activity.
Sentenced to twenty years' imprisonment, he was freed in 1963.
Even in 1968, at the height of Nicolae Ceau?escu's popularity, he confided in his diary that he viewed the regime as disastrous and doomed to fall.
