List of NBA retired numbers

As a way to honor key contributors including players, coaches, fans, broadcasters and announcers, National Basketball Association (NBA) teams often retire their jersey numbers, win totals or microphones. In the case of jersey numbers, they are usually no longer available for future players to wear, although they can ask for permission from players whose jerseys are retired. Teams usually display these numbers by hanging banners on the rafters inside their home arena. As of December 2023, only two teams in the NBA do not have any retired numbers: the Los Angeles Clippers and the Toronto Raptors. Two players have had their numbers retired by teams they did not play for, and only one player (Bill Russell) had his number retired league wide.
