Polyna Savridi (died 1980, Calgary, Alberta) was an American operatic soprano and voice teacher. As a singer she was primarily active on the international stage during the 1960s, and only performed infrequently afterwards. She taught briefly on the voice faculties of Columbia University and the Jacobs School of Music during the early 1960s before settling at the University of Calgary where she was a professor of voice from 1963 until her death from cancer seventeen years later. She is best remembered for her recordings of Greek folk songs for Concord Records and as a winner of the Metropolitan Opera National Council Auditions.
