As reported by NBA.com, Durant will collect the Maurice Podoloff Trophy for the very first time after amassing 1,232 points and 119 first-placed votes from the panel. James came second with 891 points, with Blake Griffin, Joakim Noah and James Harden rounding off the top five.
Such a win - the first of Durant's career - was expected, with the 25-year-old having produced a number of truly sublime performances for Scott Brooks' team in recent months.
Averaging 32 points, 7.4 rebounds and 5.5 assists per game, Durant became even more influential for the Thunder with fellow All-Star Russell Westbrook having missed long spells with a knee injury.
A four-time scoring champion, the former Texas Longhorn etched his name into the history books back in April after breaking Michael Jordan's long-standing record of 40 consecutive 25+ point games.
Durant initially struggled during the Thunder's tough first-round playoff series against the dogged Memphis Grizzlies, but eventually helped them to prevail with a 33-point performance in a frantic game seven at Chesapeake Energy Arena.
The newly-crowned MVP will certainly need to be at his very best if the Thunder are to return to the Finals for the first time since 2012, with OKC having suffered a heavy 122-105 loss in game one of their Western Conference semi-final matchup against the Los Angeles Clippers on Monday night.
