Tender Is the Night is a novel by American writer F. Scott Fitzgerald. It was his fourth and final completed novel, and was first published in Scribner's Magazine between January–April, 1934 in four issues. The title is taken from the poem "Ode to a Nightingale" by John Keats.

In 1932, Fitzgerald's wife Zelda Sayre Fitzgerald was hospitalized for schizophrenia in Baltimore, Maryland. The author rented the "la Paix" estate in the suburb of Towson to work on this book, the story of the rise and fall of Dick Diver, a promising young psychoanalyst, and his wife, Nicole, who is also one of his patients. It was Fitzgerald's first novel in nine years, and the last that he would complete. While working on the book he several times ran out of cash and had to borrow from his editor and agent and write short stories for commercial magazines. The early 1930s, when Fitzgerald was conceiving and working on the book, were the darkest years of his life and, accordingly, the novel has its bleak elements.

In 1998, the Modern Library ranked Tender Is the Night 28th on its list of the 100 best English-language novels of the 20th century.

The 1962 film Tender Is the Night, based on the novel, starred Jason Robards and Jennifer Jones as the Divers. The song "Tender Is the Night", from the movie soundtrack, was nominated for the 1962 Academy Award for Best Song.

Francis Scott Key Fitzgerald (1896-1940) was an American author of novels and short stories, whose works are the paradigmatic writings of the Jazz Age, a term he coined. He is widely regarded as one of the greatest American writers of the 20th century. Fitzgerald is considered a member of the "Lost Generation" of the 1920s. He finished four novels: This Side of Paradise, The Beautiful and Damned, The Great Gatsby (his most famous), and Tender Is the Night. A fifth, unfinished novel, The Love of the Last Tycoon, was published posthumously. Fitzgerald also wrote many short stories that treat themes of youth and promise along with age and despair.

Fitzgerald's work has been adapted into films many times. His short story, "The Curious Case of Benjamin Button", was the basis for a 2008 film. Tender is the Night was filmed in 1962, and made into a television miniseries in 1985. The Beautiful and Damned was filmed in 1922 and 2010. The Great Gatsby has been the basis for numerous films of the same name, spanning nearly 90 years; 1926, 1949, 1974, 2000, and 2013 adaptations. In addition, Fitzgerald's own life from 1937 to 1940 was dramatized in 1958 in Beloved Infidel.
