Salvator Mundi (Latin for Savior of the World) is a painting attributed in whole or part to the Italian High Renaissance artist Leonardo da Vinci, dated c. 1499–1510. Long thought to be a copy of a lost original veiled with overpainting, it was rediscovered, restored, and included in an exhibition of Leonardo's work at the National Gallery, London, in 2011–2012. Christie's, which sold the work in 2017, stated that most leading scholars consider it an original work by Leonardo, but this attribution has been disputed by some leading specialists.

The painting was sold at auction for $450.3 million in 2017 by Christie's in New York to Prince Badr bin Abdullah Al Saud, setting a new record for the most expensive painting ever sold at public auction. It was reported that he was a stand-in bidder for the Saudi Arabian Crown Prince Mohammed bin Salman. The painting has not been publicly exhibited since the 2017 Christie's auction.
