Adèle Hugo was the fifth and youngest child of French writer Victor Hugo. She is remembered for developing schizophrenia as a young woman, which led to a romantic obsession with a British military officer who rejected her. Her story has been retold in film and books, such as François Truffaut's 1975 film The Story of Adèle H.

Adèle Foucher was the wife of French writer Victor Hugo, with whom she was acquainted from childhood. Her affair with the critic Charles Augustin Sainte-Beuve became the raw material for Sainte-Beuve's 1834 novel, Volupté. Adèle wrote a biography of her husband, published in 1863.
