Eraclie Sterian (also known as Eracle or Eracli Sterian; November 23, 1872 – 1948) was a Romanian physician, writer, and political activist, known for introducing sexology and sex education in his country. Trained as a pathologist, he established his reputation as a popularizer of conventional and alternative medicine (primarily hydrotherapy), putting out the influential magazine Medicul Poporului. His early work also dealt with life extension practices and warnings about the effects of pollution. Sterian was additionally a publisher of textbooks and literary works, and author of dramas—including the pro-natalist propaganda play, Tout pour l'enfant, performed at at the Théâtre Antoine in 1913.
