Jean-François Portaels or Jan Portaels (3 April 1818 – 8 February 1895) was a Belgian painter of genre scenes, biblical stories, landscapes, portraits and Orientalist subjects. He was also a teacher and director of the Academy of Fine Arts of Ghent and the Académie Royale des Beaux-Arts in Brussels. He is regarded as the founder of the Belgian Orientalist school. During his time, he was praised as the premier painter of 'everyday elegance and feminine grace.'
