Stephan Roll (pen name of Gheorghe Dinu, also credited as Stéphane, Stefan or Ștefan Roll; June 5, 1904 – May 14, 1974) was a Romanian poet, editor, film critic, and communist militant. An autodidact, he played host to the Romanian avant-garde at his father's dairy shop, publishing his work in short-lived reviews and in two volumes of poetry. As one of the editors of the magazine unu, he turned from Constructivism, Futurism and jazz poetry to the more lyrical format of Surrealism. Roll's political radicalism seeped into his avant-garde activity, and produced a split inside the unu group; Roll's faction discarded Surrealism in favor of proletarian literature, and affiliated with the underground Romanian Communist Party.
