Sabina Zimering (née Szwarc; February 24, 1923 – September 6, 2021) was a Polish-American ophthalmologist and memoirist known for sharing her experiences during the Holocaust. Born in Poland, she survived the Holocaust living in Germany under an assumed identity as a Catholic Pole. After the war, she resumed her studies and earned a medical degree at Munich Medical College, one of the only women and Jewish students to do so. She immigrated to the United States to join what family remained after the Holocaust, and practiced ophthalmology. In 2001, she published her memoirs, Hiding in the Open: A Holocaust Memoir, which has twice been adapted as a play.
