La Liga Argentina de Básquetbol (in English "The Argentine Basketball League"), previously known as the Torneo Nacional de Ascenso (abbreviated "TNA", in English "National Promotion Tournament") is the second division of the Argentine basketball league system.

The La Liga's predecessor is the Torneo Federal de Básquetbol, which became the third division when the LLA was created in 1992.

History The competition was established in 1992, originally named "Torneo Nacional de Ascenso" (National Promotion Tournament), therefore then second division Primera Nacional B became the third division. The new tournament featured a division with sixteen participants, one direct promotion, and two relegations. Additionally, a "relegation playoff" series was held between the second-to-last team in the Liga Nacional and the runner-up of the Torneo Nacional, a format that ran from the inaugural season (1992-93) until the 1998-99 season.

Until the 2000–01 season, the tournament had sixteen teams; the following season saw fourteen, a trend that lasted two seasons before returning to the original number the next. However, this number fluctuated for several seasons. Throughout these seasons, the competition format consisted of two regular phases. In the first phase, teams were divided according to their geographical location in Argentina, and in the second phase, they were divided according to the results obtained in the first stage. In the 2008-09 season, an additional stage was added to the tournament: the playoff for the second promotion spot. This included the teams eliminated in the semifinals and the team that lost the final.

In 2011, the league decided to invite more participants, reaching twenty-one teams, and then settling at twenty for 2012. The 2011–12 season was the last to use the old format, as in 2012–13 a new system was implemented whereby teams from the northern region of the country would not face those from the southern region until the later stages, thus ensuring that both regions had guaranteed participation throughout the tournament.

In 2013, before the start of the 2013–14 season, the "Asociación de Clubes de Básquet" (ACB), organizer of the top two national divisions, decided to implement a relegation freeze in the top division. This affected the TNA, reducing the number of teams competing by two.

In 2014, before the start of the 2014–15 season, the organization decided to hold the season without relegations to the Torneo Federal de Básquetbol (Federal Basketball Tournament) but with promotions to the Liga Nacional (National League), thus maintaining the number of teams in the tournament.El TNA se jugará sin descensos la temporada 2014/15 at pickandroll.com.ar, 18 Jun 2014 (archived) That same year, a few months after announcing the league's closure, the number of teams was increased to 24.El Torneo Nacional de Ascenso recargado on lnb.com.ar, 5 Sep 2014 (archived)

In 2015, the league expanded again, going from 24 to 28 teams, further regionalizing the competition. However, this plan failed, and the 2015-16 season was played with 26 teams, a number that was repeated the following season.

Finally, the league reached 28 teams for the 2017–18 season, the same season in which the tournament was renamed "La Liga Argentina" (The Argentine League). In that same tournament, a particular event occurred when Club Atlético Temperley was suspended from the tournament for repeated offenses, including several intrusions by the club president onto the playing field and the disregard for the measures taken by the organization by both the club and the president.El HTD suspende la afiliación de Temperley on laliganacional.com.ar, 10 Apr 2018 As a result, Temperley's place was suspended for 120 days, while the teams that had to compete to avoid relegation, Echagüe de Paraná and Gimnasia de La Plata, maintained their place in the league.Resolución de la Mesa Directiva de AdC on laliganacional.com.ar. 11 Apr 2018

Competition format La Liga Argentina consists of 34 teams, which are divided into two conferences, "norte" and "sur", with 17 teams per zone. The competition format is similar to that of Liga Nacional, with a regular season divided into two stages. In the first stage, teams from the same division compete in a double round-robin tournament format, with standings determined by a points system.

The twelve best placed teams of each zone qualify to the post season, with stages of reclassification, quarter finals, semifinals, and finals. The four best placed teams (1st to 4th) of each zone qualify directly to quarter finals while teams positioned 5th to 12th must play a reclassification stage (where teams play each other in order to qualify to quarter finals).
