Savinien de Cyrano de Bergerac ( SIRR-ə-noh də BUR-zhə-rak, – BAIR-, French: [savinjɛ̃ d(ə) siʁano d(ə) bɛʁʒəʁak]; 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 17th century. Today, he is best known as the inspiration for Edmond Rostand's most noted drama, Cyrano de Bergerac (1897), which, although it includes elements of his life, also contains invention and myth.

Since the 1970s, there has been a resurgence in the study of Cyrano, demonstrated in the abundance of theses, essays, articles and biographies published in France and elsewhere.
