1919 Argentine Primera División

The 1919 Argentine Primera División was the 28° season of top-flight football in Argentina. The official "Asociación Argentina de Football" (AFA) league championship was abandoned mid season by the majority of the clubs, which joined the new "Asociación Amateurs de Football" (AAmF) while six clubs remained with the official body.

In the AFA league, Boca Juniors was crowned champion with 14 fixtures to be played, while Racing Club won its 7° league title at AAmF.

Club Eureka debuted in the AFA championship, while Vélez Sársfield played its first Primera División championship in the AAmF after being disaffiliated from the official body.
