The 1948 Argentine Primera División was the 57th season of top-flight football in Argentina. The season began on April 18 and ended on December 12. Due to a players' strike demanding better working conditions, relegations were suspended until the conflict was solved. As the championship continued normally and the Ministery of Labour ruled the maximum salary for football players would be mn$ 1,500, several players emigrated in search of better oportunities, most to Colombia which was not affiliated to FIFA by then. Some of the most notable footballers that emigrated were Adolfo Pedernera, Alfredo Di Stéfano, Pipo Rossi, Antonio Sastre, René Pontoni, and Julio Cozzi. Gimnasia y Esgrima (LP) returned to Primera, while no teams were relegated. Independiente won its 5th title.
