Mona Lisa (also known as La Gioconda or La Joconde, or Portrait of Lisa Gherardini, wife of Francesco del Giocondo) is a portrait by the Italian artist Leonardo da Vinci. It is a painting in oil on a poplar panel, completed circa 1503–1519 and bought by king Francis I of France. It is now the property of the French State and it is on permanent display at the Musée du Louvre in Paris.
The painting is a half-length portrait and depicts a seated woman, Lisa del Giocondo, whose facial expression has been frequently described as enigmatic. The ambiguity of the subject's expression, the monumentality of the composition, and the subtle modeling of forms and atmospheric illusionism were novel qualities that have contributed to the continuing fascination and study of the work. The image is widely recognised, caricatured, and sought out by visitors to the Louvre, and it is considered the most famous painting in the world.
