The Portrait of Emperor Maximilian I is an oil painting by Albrecht Dürer, dating to 1519 and now at the Kunsthistorisches Museum of Vienna, Austria. It portrays the emperor Maximilian I. In 1518, during the Diet of Augsburg, Maximilian called Dürer to portray him. The artist met the emperor in the castle and made a pencil drawing of him, from which he later painted the panel portrait. On the drawing's martig, he noted: "Is the emperor Maximilian that I Albrecht Dürer portrayed in Augsburg, up in the high palace, in his small room, Monday 28 June 1518".
