Guidobaldo II della Rovere
Guidobaldo II della Rovere was an Italian condottiero, who succeeded his father Francesco Maria I della Rovere as Duke of Urbino from 1538 until his death in 1574. He was a member of the House of La Rovere. Guidobaldo was an important patron of the arts in general, and of Titian in particular, commissioning his own portrait, and buying Titian's Venus of Urbino.

The portrait of Venus of Urbino has acquired its name from the Duchy of Urbino through Guidobaldo's title as the Duke of Urbino.
