Durant was born on September 29, 1988, in Washington, D.C., to Wanda (nee Durant) and Wayne Pratt. When Durant was an infant, his father deserted the family; Wanda and Wayne eventually divorced, and Durant's grandmother Barbara Davis helped raise him. By age 13, his father re-entered his life and traveled the country with him to basketball tournaments. Durant has one sister, Brianna, and two brothers, Tony and Rayvonne.

In February 2007, Durant received an invitation to the United States national team training camp. Despite a strong performance, he was cut from the team when its roster was trimmed to its twelve-player limit. Coach Mike Krzyzewski cited the experience of the remaining players as the deciding factor in making the cut. Durant was finally selected to the national team at the 2010 FIBA World Championship and became their leader as other All-Stars were unavailable, a role he downplayed. At the tournament, he led Team USA to its first FIBA World Championship since 1994, earning MVP honors in the process. His final averages for the competition were 22.8 points, 6.1 rebounds, 3.1 assists, and 1.4 steals per game in nine games.  At the 2012 Olympics, Durant set the record for total points scored in an Olympic basketball tournament. With averages of 19.5 points, 5.8 rebounds, 2.6 assists, and 1.6 steals per game, he helped the national team go undefeated en route to a gold medal. In the tournament's final game, he led all scorers with 30 points.  Less than a month before the start of the 2014 FIBA Basketball World Cup, Durant announced that he would be dropping out of the competition, citing mental and physical exhaustion as reasons for his departure. He rejoined Team USA in 2016 for the Olympics, where he led them to a gold medal. In recognition of his performances, Durant was named the 2016 co-USA Basketball Male Athlete of the Year, along with Carmelo Anthony, for the second time in his career.
