This is alist of National Basketball Association players whose last names begin with B.
The list also includes players from the American National Basketball League (NBL), the Basketball Association of America (BAA), and the original American Basketball Association (ABA). All of these leagues contributed to the formation of the present-day NBA.
Individuals who played in the NBL prior to its 1949 merger with the BAA are listed in italics, as they are not traditionally listed in the NBA's official player registers.
