Klementyna Hoffmanowa, born Klementyna Tańska (23 November 1798 – 21 September 1845) was a Polish novelist, playwright, editor, translator, teacher and activist. She was the first woman in Poland to support herself from writing and teaching, as well as one of Poland's first writers of children's literature.
She made her debut in 1819 with a moralizing treatise A Souvenir After a Good Mother. In the 1820s, she edited a popular magazine for children and published several children books, that have won a wide audience over several generations. She also published a number of novels, including: The Letters of Elżbieta Rzeczycka to her friend Urszula (1824) and, arguably her best known work, The Diary of Countess Françoise Krasinska (1825), translated into several languages, and recounted as one of the first Polish psychological novels.
