The Death of Actaeon is a late work by the Italian Renaissance painter Titian, painted in oil on canvas from about 1559 to his death in 1576 and now in the National Gallery in London. It is very probably one of the two paintings the artist stated he had started and hopes to finish in a letter to their commissioner Philip II of Spain during June 1559. However, most of Titian's work on this painting possibly dates to the late 1560s, but with touches from the 1570s. Titian seems never to have resolved it to his satisfaction, and the painting apparently remained in his studio until his death in 1576. There has been considerable debate as to whether it is finished or not, as with other very late Titians, such as the Flaying of Marsyas, which unlike this has a signature, perhaps an indication of completion.

Tiziano Vecelli or Vecellio, Latinized as Titianus, hence known in English as Titian, was an Italian (Venetian) Renaissance painter of Lombard origin, considered the most important member of the 16th-century Venetian school. He was born in Pieve di Cadore, near Belluno. During his lifetime he was often called da Cadore, 'from Cadore', taken from his native region.
