Françoise Sagan (; 21 June 1935 – 24 September 2004) – real name Françoise Quoirez – was a French playwright, novelist, and screenwriter. Hailed as "a charming little monster" by François Mauriac on the front page of Le Figaro, Sagan was known for works with strong romantic themes involving wealthy and disillusioned bourgeois characters. Her best-known novel was her first – Bonjour Tristesse (1954) – which was written when she was a teenager.
