Mihail Cruceanu (December 13, 1887 – July 7, 1988) was a Romanian poet.
He was born in Iași to Mihail Cruceanu, a doctor, and his wife Ecaterina (née Petrovanu). He attended high school in Ploiești and Pitești, earning his degree in 1906 at Bucharest's Saint Sava High School. Cruceanu enrolled in the University of Bucharest, where he took degrees in law (1911) and literature and philosophy (1913). He subsequently taught high school at Alexandria, Craiova and Bucharest. He made his poetic debut in Revista literară in 1904. Although he associated with the Literatorul circle of Alexandru Macedonski, he was closer to Ovid Densusianu's Vieața Nouă group. His first published volume was the 1912 Spre cetatea zorilor. Between 1911 and 1913, he interviewed a series of cultural figures, recording the encounters in Rampa; these included Macedonski, Densusianu, Alexandru Vlahuță, Ioan Alexandru Brătescu-Voinești, Dimitrie Anghel, Ioan A. Bassarabescu and Mihail Dragomirescu. Reviews that published his work include Farul, Vieața Nouă, Sărbătoarea eroilor, Versuri și proză, Revista celorlalți, Flacăra, Adevărul literar, Îndreptar, Românul, Zorile, Revista Fundațiilor Regale, Luceafărul, Viața Românească and România Literară.
