A person being painted is typically referred to as a "model." In artistic contexts, they may also be called a "subject" of the artwork. If the painting is a portrait, they can specifically be referred to as a "portrait subject."

Put it this way: "Why did Leonardo da Vinci name this painting "La Gioconda"? Very simple. It is usually known as the Mona Lisa, which is short for Madonna Lisa (the woman's first name). She is better known as the third wife of a merchant from Florence named Francesco di Bartholommeo del Giocondo. "La Gioconda" is Italian for "the Giocondo woman" (-do is masculine, -da is feminine). So we might call the painting Mrs. Giocondo, or Mme Gioconda, or Frau Giocondo, or Signora Gioconda.
