Jordan Spieth equalled the lowest winning score in Masters history to cap a record-breaking display at Augusta and win his first major.
The 21-year-old American, second on his debut last year, shot a two-under 70 to triumph on 18 under.
England's Justin Rose hit 70 to finish 14 under, joint second with three-time champion Phil Mickelson (69) who ended runner-up in a major for the 10th time.
World number one Rory McIlroy tied for fourth on 12 under after a 66.
The story going into the Masters had been all about the Northern Irishman's quest to become just the sixth man to win the Grand Slam of all four of golf's majors.
But it was Spieth, the new world number two, who dominated the headlines on each day, equalling Tiger Woods's winning score of 18 under in 1997, when the former world number one won his first Green Jacket.
