The 2015 PGA Championship was the 97th PGA Championship, held August 13–16 on the Straits Course of Whistling Straits in Kohler, Wisconsin (the course is physically in Haven but holds a Kohler mailing address due to its Kohler Company ownership). It was the third PGA Championship at Whistling Straits, which previously hosted in 2004 and 2010, as well as the United States Senior Open in 2007, all held on the Straits Course.

Jason Day won his first major championship title with a total score of 268 (−20), at the time the lowest score in relation to par ever recorded in a major (a mark since equaled by Henrik Stenson during his win at the 2016 Open Championship, Dustin Johnson at the 2020 Masters Tournament, and Cameron Smith at the 2022 Open Championship). Jordan Spieth, attempting to win his third major of the year, finished in second place three strokes behind. The second-place finish allowed Spieth to surpass Rory McIlroy as number one in the Official World Golf Ranking. Day was the fifth Australian to win the PGA Championship, the first in twenty years.

Final round Sunday, August 16, 2015

Jason Day set a major championship scoring record on the way to a three-stroke victory and his first career major. After a round of 67 (−5) he finished the tournament at 20-under-par, breaking the previous major scoring record set by Tiger Woods at the 2000 Open Championship. Jordan Spieth, looking to join Woods and Ben Hogan with three major victories in a year, began the final round two strokes behind but was never able to close that deficit, finishing three shots behind. Spieth finished the year 54-under-par at the majors, also surpassing Woods' record from 2000. Branden Grace and Justin Rose also got to within two shots of the lead but fell from contention after double bogeys at the 10th and 13th, respectively.
