Spurs guard Stephon Castle is the 2024-25 Kia NBA Rookie of the Year. San Antonio is the first team with back-to-back winners since the Minnesota Timberwolves in 2014-15 (Andrew Wiggins) and 2015-16 (Karl-Anthony Towns).

Castle follows 2023-24 recipient Victor Wembanyama and is the fourth ROY winner in franchise history, also joining David Robinson and Tim Duncan. Memphis Grizzlies forward Jaylen Wells and Atlanta Hawks forward Zaccharie Risacher were the other finalists for the award.

Castle's win marked the second time in more than a half-century that one franchise went back-to-back with the top-rookie honor. Minnesota’s Andrew Wiggins (now of Miami) and Karl-Anthony Towns (now of New York) were voted rookies of the year in 2015 and 2016, respectively.
