The Feminine Mystique is a book by American author Betty Friedan, widely credited with sparking second-wave feminism in the United States. First published by W. W. Norton on February 19, 1963, The Feminine Mystique became a bestseller, initially selling over a million copies. Friedan used the book to challenge the widely shared belief that "fulfillment as a woman had only one definition for American women after 1949—the housewife-mother."
