Campeonato de Fútbol Femenino de Primera División B

The Campeonato de Fútbol Femenino de Primera División B (First Division B Women's Football Championship), also known as the Segunda División Femenina (Women's Second Division), is the second-highest division of women's football in Argentina.

It was established in 2016, after the Argentine Football Association decided to separate the Campeonato de Fútbol Femenino into two divisions, based on the final results in the 2015 season. The creation of the second division allowed more teams to enter Primera División B. Since the 2018-19 season, the worst-placed teams have been relegated to the Primera División C, the third division.

2016
The first season began on 3 April 2016 with 14 teams that added the debuting teams and the teams that had descended from the Primera División in the 2015 season. These clubs were Almagro, Atlanta, Bella Vista (Córdoba), Defensores Unidos, Defensores del Chaco, Deportivo Morón, Excursionistas, Hebraica, El Porvenir, Liniers, Lujan, Villa San Carlos, Leandro N. Alem and Fernando Cáceres FC, although Bella Vista and Leandro N. Alem left before starting the season while Almagro did during it. The season was a round trip of everyone against everyone. On 25 September, Villa San Carlos was proclaimed champion and were promoted to Primera División A while El Porvenir and Atlanta, which finished second and third respectively, were also promoted.
