Anastacia (born Anastacia Lyn Newkirk on September 17, 1968 or 1973) is an American pop singer and songwriter. She has been highly successful in Europe, Oceania, and South Africa but has not had as much success in her native United States. Despite the lack of American success, she has sold over 20 million records worldwide.

She is known for her powerful, raspy voice, and she is a dramatic soprano and is famous for her ability to hit high notes in her chest voice. Her vocal sound and style has sometimes led her to be initially mistaken for an African-American singer.
