La maja desnuda, or Naked Maja, is a painting by Francisco Goya (1746–1828). It hangs in the Prado in Madrid. Next to it is the clothed version, La maja vestida.
The paintings were originally hung one in front of the other, with the more decent picture on a pulley system allowing it to be raised to expose its naughtier pair.
Maja in Spanish refers to a woman from the lower classes of Madrid society.
The paintings play a central role in Jostein Gaarder's novel, Maya.
