Henric Ștefan Streitman (first name also Henric Șt., Enric, Henri or Henry, last name also Streitmann, Streittman, Ștraitman; 1873 – circa March 30, 1950) was a Romanian journalist, translator and political figure, who traversed the political spectrum from socialism to the far-right. A physicist, social commentator and publisher, in his early years he was a promoter of natural selection ideas as well as a translator of Marxist and naturalist literature. Respected for both his polemical stances and his erudition, he was also rendered controversial by his inconsistencies and his alleged corruption. Often struggling financially, Streitman set up several short-lived periodicals, and involved himself in the cultural and political debates, from 1889 to the time of his death.
