2004–05 in Argentine football

The 2004–05 Argentine First Division season saw Américo Gallego's Newell's Old Boys win the Apertura title after a fierce battle against Vélez Sársfield for the supremacy. Vélez soon got over the disappointment after winning the Clausura with Banfield finishing second despite playing most of the tournament with a young squad because they were also competing the Copa Libertadores de América.

Huracán de Tres Arroyos and Almagro were relegated to the Nacional B after lackluster performance while Argentinos Juniors and Instituto played the promotion against Atlético de Rafaela and Huracán, respectively. Both won their series and were able to stay in the top category of the Argentine Football.
