The Campeonato Nacional de la Primera B del Fútbol Profesional Chileno (English: National Championship of the First B of Chilean Professional Football) is the second tier in the Chilean football league system, and is organized by the Asociación Nacional de Fútbol Profesional. It was established in 1952 as Segunda División, and later renamed in 1996 to the current name. Since 1954, automatic promotion to and relegation from the Campeonato Nacional has been granted, although Palestino and Rangers were promoted to the top flight in the first season.
