Ida Rauh (March 7, 1877 – February 28, 1970) was an American suffragist, actress, sculptor, and poet who helped found the Provincetown Players in 1915. The players, including Susan Glaspell, George Cram Cook, John Reed, Hutchins Hapgood, Eugene O'Neill, and others, first performed in a structure owned by Mary Heaton Vorse in Provincetown, Massachusetts. Later, the group moved to a theater on MacDougal Street in Greenwich Village. Rauh directed the first production of O'Neill's one-act play Where the Cross Is Made for the opening of the permanent Provincetown Playhouse at 133 Macdougal Street in November 1918, and in the Village she became known for her intensely emotional acting.
