Jamie Lee Curtis (born November 22, 1958) is an American actress. Although she was initially known as a "scream queen" because of her starring roles in many horror films early in her career such as Halloween, The Fog, Prom Night and Terror Train, Curtis has since compiled a body of work that covers many genres. Her 1998 book, Today I Feel Silly, and Other Moods That Make My Day, made the best-seller list in The New York Times. She is married to actor Christopher Guest (Lord Haden-Guest) and, as the wife of a lord, is titled Lady Haden-Guest, but she chooses not to use the title when in the United States. She is currently the spokeswoman for Activia. She is also a blogger for The Huffington Post online newspaper.

Curtis was born in Los Angeles, California, the child of actors Tony Curtis and Janet Leigh. Her paternal grandparents were Hungarian Jewish immigrants. Curtis's parents divorced in 1962 and her mother then married Robert Brandt. Curtis has an older sister, Kelly Curtis, who is also an actress, and several half-siblings (all from her father's remarriages), Alexandra, Allegra, Ben, and Nicholas Curtis (who died in 1994 of a drug overdose). Curtis attended both Westlake School in Los Angeles and Beverly Hills High School, but graduated from Choate Rosemary Hall. Returning to California in 1976, Jamie attended the University of the Pacific in Stockton, California. Jamie considered majoring in social work, but left after a semester in order to pursue a career in acting.

Curtis's film debut was the 1978 horror Halloween, playing the role of Laurie Strode, the only central teenage character in the film who is not killed. The film was a major success and was considered the highest grossing independent film of its time, earning status as a classic horror film. Curtis was subsequently cast in several horror films, garnering her the title of a "scream queen".
