Savinien de Cyrano de Bergerac (6 March 1619 – 28 July 1655) was a French novelist, playwright, epistolarian and duelist.

A bold and innovative author, his work was part of the libertine literature of the first half of the seventeenth century. Today he is best known as the inspiration for Edmond Rostand's most noted drama Cyrano de Bergerac which, although it includes elements of his life, also contains invention and myth.
