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.
