Valeriu Marcu (1899–1942) was a Romanian poet, writer and historian. He wrote the first biography of Vladimir Lenin.
Marcu, who was Jewish, migrated from Germany to Austria, and then to France, where he and his wife Eva settled in Nice in 1933. In 1940 Varian Fry helped the family get papers to leave France.
