《救世主》（意大利语：Salvator Mundi）是列奥纳多·达·芬奇的其中一幅画作。過去它曾隱沒很長一段時間，甚至一度被認為是达芬奇学生的作品。2004年，紐約的罗伯特·赛门（Robert Simon）以低价买下該画作。並交由專家修復與鑑定後，2011年終於重現在世人面前。
Salvator Mundi is a painting of Christ as Salvator Mundi recently attribute...展开d to Leonardo da Vinci, who is known to have painted the subject. It was lost and later rediscovered, and restored and exhibited in 2011. The painting shows Christ, in Renaissance garb, giving a benediction with his raised right hand and crossed fingers while holding a crystal sphere in his left hand.
In France, Leonardo da Vinci painted the subject, Jesus Christ, for Louis XII of France between 1506 and 1513. The recently authenticated work was once owned by Charles I of England and recorded in his art collection in 1649 before being auctioned by the son of the Duke of Buckingham and Normanby in 1763. It next appeared in 1900, damaged from previous restoration attempts and its authorship unclear, when it was purchased by a British collector, Sir Frederick Cook. Cook's descendants sold it at auction in 1958 for £45. The painting was rediscovered, acquired by a US consortium of art dealers in 2005, and authenticated as by Leonardo. It was exhibited by London's National Gallery during the Leonardo da Vinci: Painter at the Court of Milan from 9 November 2011 to 5 February 2012.
