Cooper Flagg Parents have been a major topic of conversation as the Duke basketball phenom prepares to take the NBA by storm. Born on December 21, 2006, in Newport, Maine, Cooper Flagg is widely regarded as one of the most gifted basketball prospects in recent memory. He skipped his senior year of high school entirely to attend Duke University, where he quickly established himself as a dominant force on the court.
Cooper has come to the top in a remarkable way. His first college scholarship invitation was in eighth grade, which also speaks of the exceptional talent that he possessed at a very tender age. He nationalized himself at Duke, bringing his team to the brink of the NCAA Tournament and gaining a huge reputation as a generational talent.
Cooper was also chosen as the first overall in the NBA Draft on June 25, 2025, by the Dallas Mavericks a moment he termed as surreal. “This is the moment I’ve dreamed about my entire life,” he told ESPN. Alongside him every step of the way have been his deeply supportive family, and most notably, his parents.
Who Are Cooper Flagg Parents?
Cooper Flagg Parents are Kelly Flagg and Ralph Flagg – and remarkably, both are former college basketball players themselves. Cooper Flagg parents married in the early 2000s and have been the driving force behind his basketball development since childhood.
Kelly Flagg played for the University of Maine in the late 1990s and was part of a historic team that won the program’s first-ever NCAA Tournament game, upsetting Stanford University during the 1998–99 season. That team was later inducted into the school’s Sports Hall of Fame in 2021. Ralph Flagg played basketball at Eastern Maine Community College. The couple met shortly after their college days, bonding over their mutual love for the game.
Cooper Flagg Parents have been regular courtside supporters in his career and have been known to have a passionate and even viral support. When Cooper dunked twice with his hands during the ACC tourney in 2025, Kelly was caught on camera celebrating maniacally because of it, a photo that quickly disseminated on social media. Ralph, on the other hand, follows a strict superstition of never wearing Duke gear on game days.
Cooper has openly credited his father for much of his development as a player. “I grew up in the gym with my dad – late nights, early mornings, with him just rebounding for me,” he shared. The dedication of Cooper Flagg Parents to his growth has clearly paid off at the highest level.
