Breakfast at Tiffany's is a novella by Truman Capote published in 1958. The main character, Holly Golightly, is one of Capote's best-known creations and an American cultural icon.

Breakfast at Tiffany's first appeared in the November 1958 issue of Esquire. Shortly afterward, a collection of the novella and three short stories by Capote was published by Random House. The collection has been reprinted several times; the novella has been included in other Capote collections.

The novella was loosely adapted into the 1961 movie Breakfast at Tiffany's starring Audrey Hepburn and directed by Blake Edwards. The movie was transposed to circa 1960 rather than the 1940s, the period of the novella.
