Spain's Jon Rahm kept his nerve and patience to win a first Masters, swinging an exciting final day in his favour from American Brooks Koepka.
Rahm, 28, carded a three-under 69 to finish on 12 under and win by four shots as Koepka, who led by two going into the final round, signed for a 75.
Koepka ended joint second with veteran Phil Mickelson, who shot a stunning seven-under 65 to finish eight under.
Former champions Jordan Spieth and Patrick Reed were a shot further back.
Defending champion Scottie Scheffler finished in a group on four under, along with England's US Open champion Matt Fitzpatrick, who was the highest finisher from Great Britain and Northern Ireland.
