Nina Hagen (born 11 March 1955) is a German singer and actress.
Hagen was born as Catharina Hagen in the former East Berlin, East Germany, the daughter of Hans Hagen (also known as Hans Oliva-Hagen), a scriptwriter, and Eva-Maria Hagen, an actress and singer. Her paternal grandfather died in the Sachsenhausen concentration camp (one of her great-grandparents was Jewish). Her parents divorced when she was two years old, and growing up she saw her father infrequently. At age four, she began to study ballet, and was considered an opera prodigy by the time she was nine.
When Hagen was 11, her mother married Wolf Biermann, an anti-establishment singer-songwriter. Biermann's political views later influenced young Hagen.
