Sarah Kane (3 February 1971 – 20 February 1999) was an English playwright. She is known for her plays that deal with themes of redemptive love, sexual desire, pain, torture—both physical and psychological—and death. Her works are characterized by poetic intensity, pared-down language, and exploration of theatrical form. In her earlier works, she made use of extreme and violent stage action.

Kane and scholars of her work, such as Graham Saunders, have identified some of her inspirations as expressionist theatre and Jacobean tragedy. The critic Aleks Sierz saw her work as part of a confrontational style and sensibility of drama termed "in-yer-face theatre." Sierz originally called Kane "the quintessential in-yer-face writer of the 1990s" but later remarked that she seems more un-typical as time passes.

Kane's published work consists of five plays, the short film Skin, and two newspaper articles for The Guardian. She battled with depression, and her life was brought to a premature end when she committed suicide at London's King's College Hospital.
