The Germany international picked up 217 votes from selected football writers in Germany, beating his new Borussia Dortmund team-mates Mats Hummels, Robert Lewandowski and Shinji Kagawa to the prize, which has been awarded annually since 1960. Second-placed Hummels receive less than half that tally.
Dortmund's Jurgen Klopp was the overwhelming choice as coach of the year, ahead of Borussia Monchengladbach's Lucien Favre and Christian Streich of Freiburg.
"It makes me very proud because this is an award which will remain with me forever," said 23-year-old Reus, whose achievements for Gladbach last season were recognised.
"This recognition is also an incentive to keep going and get even better in the new season."
Reus paid tribute to Favre, who he said is "the best coach I ever had", although he is now looking forward to improving under Klopp at the German champions.
"I am 23 and I am certainly not at the end of my development," he told Kicker.
"Things are just getting going now. Experience is certainly a defining factor and that should build up over the coming years."
