The 1970 Copa Argentina Finals were the final two-legged tie that decided the champion of the 1970 Copa Argentina. The finals were contested in two-legged home-and-away format between San Lorenzo and Vélez Sársfield. The first leg was played in Atlanta Stadium of Villa Crespo, finishing in a 2-2 tie.
The second leg was never played so the tournament was unfinished and neither San Lorenzo nor Velez Sarsfield were declared champion.[1] The champion was supposed to qualify to Copa Ganadores de Copa but this never happened.[2] [3]
