2006–07 Argentine Primera División

The 2006–07 Argentina Primera División was the 116th season of first division football in Argentina. Estudiantes (LP) won the Torneo Apertura and San Lorenzo won the Torneo Clausura.
Godoy Cruz, Nueva Chicago, and Belgrano were promoted from the 2005–06 Primera B Nacional.
At the end of the season, Belgrano and Quilmes were directly relegated to the Primera B Nacional and Huracán and Tigre promoted from Primera B Nacional after winning the relegation playoff against Godoy Cruz and Nueva Chicago respectively. Therefore, a total of four teams were relegated to the second division.

Torneo Apertura

Boca Juniors and Estudiantes LP ended up tied in points at the end of the 19 weeks of regular season. Tournament rules establish that, unlike any other position on the table, if two or more teams are equal in points at the end of play, goal difference does not count and a playoff game is required. Estudiantes won that match and was crowned as champion.
