The National Basketball Association's Rookie of the Year is an annual National Basketball Association (NBA) award given to the top rookie (s) of the regular season. Initiated following the 1952–53 NBA season, it confers the Eddie Gottlieb Trophy, named after the former Philadelphia Warriors head coach. Since the 2022–23 NBA season, winners receive the Wilt Chamberlain Trophy, named after the former Rookie of the Year winner, who also won the regular season MVP and All-Star Game MVP during his rookie season.
The winner is selected by a panel of United States and Canadian sportswriters and broadcasters, each casting first-, second-, and third-place votes (worth five points, three points, and one point, respectively).
