The 1929 Argentine Primera División was the 38th season of top-flight football in Argentina.

The top 2 of each group qualified for the final stages of the tournament, which was eventually won by Gimnasia y Esgrima (LP).

The season was marred by mass abandonment of games, defending Argentine champion Huracán withdrew from 8 of its fixtures leaving them to finish in 14th place in the group.

Colegiales returned to the first division after winning the Primera B championship last year.

As Boca Juniors and San Lorenzo finished equaled on points, they needed a playoff to decide which team went to the final and which to the 3rd/4th place playoff.
