Chantal Thomas is a French writer and historian. Her 2002 book, Farewell, My Queen, won the Prix Femina and was adapted into a 2012 film starring Diane Kruger and Léa Seydoux.

The Prix Femina is a French literary prize created in 1904 by 22 writers for the magazine La Vie heureuse. The prize is decided each year by an exclusively female jury. They reward French-language works written in prose or verse, by both women and men. The winner is announced on the first Wednesday of November each year.
