 She married fellow poet Ted Hughes in 1956, and they lived together in the United States and then in England.

Sylvia is a 2003 British biographical drama film directed by Christine Jeffs and starring Gwyneth Paltrow, Daniel Craig, Jared Harris, and Michael Gambon.

The Bell Jar is the only novel written by the American writer and poet Sylvia Plath.
 Originally published under the pseudonym "Victoria Lucas" in 1963, the novel is semi-autobiographical, with the names of places and people changed.
 The book is often regarded as a "roman à clef" since the protagonist's descent into mental illness parallels Plath's own experiences with what may have been clinical depression.
 Plath died by suicide a month after its first UK publication.
 The novel was published under Plath's name for the first time in 1967 and was not published in the United States until 1971, in accordance with the wishes of both Plath's husband, Ted Hughes, and her mother.
 The novel has been translated into nearly a dozen languages.
 The novel, though dark, is often read in high school English classes.
The Sylvia Plath effect is the phenomenon that poets are more susceptible to mental illness than other creative writers.
 The term was coined in 2001 by psychologist James C. Kaufman.
 Although many studies (e.g., Andreasen, 1987; Jamison, 1989; Ludwig, 1995) have demonstrated that creative writers are prone to experience mental illness, this relationship has not been examined in depth.
 This early finding has been dubbed "the Sylvia Plath effect", and implications and possibilities for future research are discussed.
 Kaufman's work further demonstrated that female poets were more likely to experience mental illness than any other class of writers.
 In addition, female poets were more likely to be mentally ill than other eminent women, such as politicians, actresses, and artists.
Winter Trees is a 1971 posthumous collection of poetry by Sylvia Plath, published by her husband Ted Hughes.
 Along with "Crossing the Water" it provides the remainder of the poems that Plath had written during her state of elevated creativity prior to her suicide.
Johnno is a semi-autobiographical novel written by Australian author David Malouf and was first published in 1975.

 She killed herself and her four-year-old daughter Alexandra Tatiana Elise (nicknamed "Shura") in a fashion similar to that of Sylvia Plath, well-known writer and Hughes's first wife, who six years earlier had also committed suicide, by use of a gas oven.
