Puerto Libertad is a village and municipality in Misiones Province in north-eastern Argentina.

A settlement in the area was created in the late nineteenth century with the arrival of factories which employed people to harvest yerba mate on the Paraná River.

The town, which was originally known as Villa Veinticinco de Mayo, developed steadily, and already had its first school in 1927, and a year later a post office.

In 1950, the first Development Commission was created with the name of "17 de Octubre", in honor of the Peronist Party.

Because of the political connotations of the name, the military coup that overthrew Juan Domingo Perón gave the town the name of Libertad in 1955.
