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."

Second-wave feminism was a period of feminist activity that began in the early 1960s and lasted roughly two decades, ending with the feminist sex wars in the early 1980s and being replaced by third-wave feminism in the early 1990s. It occurred throughout the Western world and aimed to increase women's equality by building on the feminist gains of the late 19th and early 20th centuries.
