Demi Moore (born Demetria Gene Guynes) is an American actress and film producer.

After making her film debut in 1981, she appeared on the soap opera General Hospital and subsequently gained recognition as a member of the Brat Pack with roles in Blame It on Rio (1984), St. Elmo's Fire (1985), and About Last Night... (1986). Her starring role in Ghost (1990), the highest-grossing film of that year, earned her a Golden Globe nomination. She had further box-office success in the early 1990s, with the films A Few Good Men (1992), Indecent Proposal (1993), and Disclosure (1994).

She portrayed Claire Donnelly in the drama film If These Walls Could Talk (1996), for which she was nominated for a Golden Globe Award and a Primetime Emmy Award. In 1996, Moore became the highest-paid actress in film history when she received an unprecedented $12.5 million salary to star in Striptease. She voiced the role of Esmeralda in The Hunchback of Notre Dame (1996) and The Hunchback of Notre Dame II (2002). Her next major role, G.I. Jane (1997), for which she shaved her head, was followed by a lengthy hiatus. She achieved further success in the following decades with the films Charlie's Angels: Full Throttle (2003), Bobby (2006), Mr. Brooks (2007), Margin Call (2011), and Rough Night (2017).

In 2019, Moore released a memoir titled Inside Out, which instantly became a New York Times Best Seller.
