The Tercera División de Fútbol Sala Masculina, formerly known as Primera Nacional B, is the fourth level according to the Spanish futsal league system. Founded in 1990, it is managed by the Real Federación Española de Fútbol.
The Tercera División de Fútbol Sala Masculina works similar to the Tercera Federación of Spanish football. It is the fourth tier like the former Tercera División, and it is divided into twenty-four groups, corresponding to the Autonomous communities of Spain, excepting Catalonia which has two groups (1 and 2), Community of Madrid (3 and 4), Canary Islands (11 –Province of Las Palmas– and 12 –Province of Santa Cruz de Tenerife–), Valencian Community (14 and 15 –Province of Alicante–), Andalusia (17 –Western Andalusia– and 18 –Eastern Andalusia–).
All the groups are made up by sixteen teams, except the groups 7 (Navarre –thirteen teams–), 11 (Canary Islands –eleven teams–), 12 (Canary Islands –fourteen teams–), 19 (Balearic Islands –fourteen teams–), 20 (La Rioja –fourteen teams–) and 21 (Cantabria –eight teams–). Group 22 (Ceuta) just has one team, Real Sociedad La Pantera; and Group 24 (Melilla) does not have any team for this current season.
Every group champion promotes directly to Segunda División B. The runner-ups qualify for the national promotion playoff, which will be a single knockout round, home and away tie.
