Throughout the league, numerous brothers have established their presence, with some evolving into household names while others are still carving out their legacies. The Harper brothers embody this dynamic, showcasing the thick bloodlines of basketball prowess that permeate their family. Ron Harper Jr. and Dylan Harper are currently in the early stages of their careers, with their father, Ron Harper, a former NBA star boasting five championship titles under his belt.
One prominent pair, the Curry brothers, have already made significant waves in the league. Stephen and Seth Curry, who grew up in Charlotte, North Carolina, each inherited their father’s basketball talent. Stephen has been a long-time member of the Golden State Warriors since being drafted in 2009, while Seth has switched between multiple teams before joining him in 2025. Their historical meeting in the NBA Conference Finals in 2019 marked the first time siblings faced each other at this level, further solidifying their bond—and healthy rivalry.
Another set of brothers making strides in the NBA are twins Keegan and Kris Murray. Hailing from Cedar Rapids, Iowa, the duo emerged from high school to collegiate stardom playing for the University of Iowa. With Keegan being drafted fourth overall by the Sacramento Kings in 2022 while Kris followed in 2023 as a member of the Portland Trail Blazers, their paths intersected in November 2023 when they faced each other for the first time. Keegan expressed excitement over this unique experience—”It’s a once-in-a-lifetime thing,” he noted, highlighting the rarity of competing against a sibling professionally.
The Antetokounmpo brothers, Giannis and Thanasis, have also made a significant impact within the league. After relocating from Greece, the brothers have established themselves as vital components of the Milwaukee Bucks’ success. Giannis, notably known as the “Greek Freak,” clinched the MVP title and was instrumental in leading the Bucks to an NBA Championship in 2021. Their close-knit bond is evident; Giannis has spoken about how Thanasis contributes to the team’s energy, emphasizing their shared commitment to winning.
Another noteworthy pair includes the Wagner brothers, Moritz and Franz, who made their mark alongside each other at the University of Michigan. Moritz, who was drafted by the Lakers, later reunited with Franz when he joined the Orlando Magic. Their shared experience and camaraderie have made their time in the NBA particularly memorable, with Moritz reflecting on the happiness derived from playing alongside his brother day-to-day.
Basketball runs deep in the Jones family as well, with Tyus and Tre Jones both making their names in the sport. Having attended Duke University, the brothers have forged their own paths in the NBA—Tyus suiting up for the Denver Nuggets and Tre for the San Antonio Spurs. Their individual journeys have led to the excitement of facing each other in a game, with Tyus recalling how such moments were dreams come true from their childhood.
The duo of Amen and Ausar Thompson also broke new ground when they made history as the first twins selected in the top 10 of the draft. Amen joined the Houston Rockets while Ausar went to the Detroit Pistons in the 2023 draft. Their matchup in early 2024 was greeted with great enthusiasm, as both brothers expressed excitement about competing against one another professionally.
Lastly, Jalen and Cody Williams, another rising pair of siblings in the league, have found success after being drafted by the Oklahoma City Thunder and the Utah Jazz, respectively. They both previously showcased their talents at the collegiate level, with Jalen noting his hopes for Cody to perhaps outshine him in the future—a sentiment underscored by the strong sibling bond they share.
As the 2026 NBA Finals continue to capture the attention of basketball fans, the thriving sibling rivalries add another layer of intrigue. With emerging talents like Dylan Harper, and established figures like the Currys and Antetokounmpos, the league not only celebrates individual achievements but also the enduring legacy of family connections that define the sport. Each brother’s journey reflects the trials, triumphs, and unique experiences shared by those who grew up together, now competing at the highest level.
