Sarah Reisen (1885–1975; her name is sometimes transliterated as Sora Reyzen or Raizin) was a Belarusian-American Yiddish poet and translator.
At home, she learned Torah portions from her father, Hebrew from the rabbi's wife, German from her mother, and Russian from her teacher.
Reisen moved then to Minsk at the age of 14, where she worked as a seamstress and a Russian tutor, and continued her studies.
She soon joined the Yiddish literary circle, writing sketches, short stories, and poems for various periodicals and publications such as Di Folkstzaytung, Der Veg, Der Fraynd, The Forward, Feder, and her brother's publication Eyropeyishe Literatur, sometimes under the pen name Sarah Kalmens.
Her translations into Yiddish include, among others, works by Tolstoy, Andreyev, Turgenev, and Pushkin.
