Cooper Flagg’s Family: All About the Duke Basketball Star’s Parents and Siblings

Cooper Flagg: A Look into the Family of the Duke Basketball Star

Cooper Flagg, the rising star of Duke University’s basketball team, has captured the hearts of many with his exceptional talent on the court. Behind his success stands a supportive and basketball-loving family that has played a significant role in shaping his career. Let’s delve into the lives of Cooper’s parents, Kelly and Ralph Flagg, as well as his siblings, Hunter and Ace.

Basketball runs in the Flagg family’s blood, with both of Cooper’s parents, Kelly Bowman Flagg and Ralph Flagg, having backgrounds as former college basketball players. The couple, who tied the knot in the early 2000s, shared a love for the sport that transcended onto their three sons. Their eldest son, Hunter, was born in 2004, followed by Cooper and his twin brother, Ace, in 2006.

Growing up in Newport, Maine, the Flagg brothers had basketball embedded into their daily lives. From playing in the driveway to competing in school teams, the boys shared a deep passion for the game. Ace, a three-time high school state champion, has committed to the University of Maine, while Cooper is making waves at Duke University, poised to be a top pick in the upcoming NBA draft.

Kelly and Ralph’s own basketball journey is equally inspiring. Kelly, a former player for the University of Maine, achieved a notable milestone in the late ’90s when her team secured the program’s first NCAA tournament win. Ralph, on the other hand, showcased his skills on the court for Eastern Maine Community College. Their shared love for basketball brought them together and eventually led to a beautiful family with four children.

The road to building their family was not without challenges. After facing complications during Kelly’s pregnancy with twins, the Flaggs welcomed Hunter and tragically lost Ryder shortly after birth. The couple’s unwavering resilience saw them through the tough times, and they later welcomed Ace and Cooper, completing their family. Cooper, in particular, showed early promise in basketball and flourished under the guidance of his father, who played a pivotal role in his development.

Cooper’s brothers have also carved out their own paths in basketball, with Hunter pursuing a degree in sports management at the University of Maine alongside Ace, who continues to excel on the court. Together, the Flagg brothers have achieved notable success, including multiple state championships and a strong presence in the basketball scene.

Kelly and Ralph’s unwavering support for their sons is evident in their superstitious game-day rituals and fervent cheers from the sidelines. Their dedication to their children’s basketball journeys was highlighted during a viral moment at the 2025 ACC Tournament, where Kelly’s passionate reaction to Cooper’s play garnered attention online. Despite facing some backlash, Kelly stood by her actions, expressing pride in her son’s accomplishments.

As Cooper continues to shine on the basketball court and make strides towards a promising future, his family remains a pillar of strength and support. The Flagg family’s story is a testament to the power of unity, dedication, and love in nurturing young talent and fostering success. With their unwavering commitment to each other, the Flaggs are undoubtedly a force to be reckoned with in the world of basketball.
