Her career began in the early 1960s on Broadway. She made her screen debut in the 1967 film The Happening, the same year she made Hurry Sundown with an all-star cast, and rose to fame with her portrayal of outlaw Bonnie Parker in Arthur Penn's Bonnie and Clyde, for which she received her first Academy Award nomination. Her most notable films include the crime caper The Thomas Crown Affair (1968), the drama The Arrangement (1969), the revisionist western Little Big Man (1970), a two-part adaptation of the Alexandre Dumas classic The Three Musketeers (1973, with The Four Musketeers following in 1974), the neo-noir mystery Chinatown (1974) for which she earned her second Oscar nomination, the action-drama disaster The Towering Inferno (1974), the political thriller Three Days of the Condor (1975), the satire Network (1976) for which she won an Academy Award for Best Actress, and the thriller Eyes of Laura Mars (1978).

Her career evolved to more mature character roles in subsequent years often in independent films, beginning with her controversial portrayal of Joan Crawford in the 1981 film Mommie Dearest. Other notable films include Supergirl (1984), Barfly (1987), The Handmaid's Tale (1990), Arizona Dream (1994), Don Juan DeMarco (1995), The Twilight of the Golds (1997), Gia (1998) and The Rules of Attraction (2002). Dunaway has also performed on stage in several plays, including A Man for All Seasons (1961–63), After the Fall (1964), Hogan's Goat (1965–67), A Streetcar Named Desire (1973). She was awarded the Sarah Siddons Award for her portrayal of opera singer Maria Callas in Master Class (1996).

Protective of her private life, she rarely gives interviews and makes very few public appearances. After romantic relationships with Jerry Schatzberg and Marcello Mastroianni, Dunaway married twice, first to singer Peter Wolf and then to photographer Terry O'Neill, with whom she had a son, Liam.
