The Claudine series consists of four early novels by French authors Colette and Henry Gauthier-Villars, published 1900–1904. Written in diary form, they describe the growth to maturity of a young girl, Claudine. Aged fifteen at the beginning of the first book, Claudine à l'école, the series describes her education and experiences as she grows up. All the books are written in first-person with the first three having Claudine herself as the narrator. The last in the series, Claudine s'en va, introduces a new narrator, Annie.
