Rosemary Elizabeth "Posy" Simmonds MBE (born 9 August 1945) is a British newspaper cartoonist and writer and illustrator of children's books. She is best known for her long association with The Guardian, for which she has drawn the series Gemma Bovery (2000) and Tamara Drewe (2005–06), both later published as books. Her style gently satirises the English middle classes and in particular those of a literary bent.
