The 1970 Primera División season was the 79th season of top-flight football in Argentina, with Independiente winning the Metropolitano championship (9th title) by goals for difference (43–42) after being equaled on points with River Plate. In the Nacional championship, Boca Juniors (coached by José María Silvero after Alfredo Di Stéfano resigned) won its 18th league title after beating Rosario Central in the final.
Starting this season, two substitutions were allowed per team during the game. That rule had been first introduced in 1959, but for injured goalkeepers only.
Unlike previous seasons, there was no team promoted from Primera B Metropolitana. Boca Juniors and Rosario Central (as champion and runner up of Nacional respectively) qualified to 1971 Copa Libertadores. On the other hand, Lanús, Quilmes and Unión (SF) were relegated.
