The first inhabitants of the region were indigenous tribes. The Portuguese dominion explored and later claimed the lands until 1822 when Brazil gained independence. In 1813, the Curitibano João Gonçalves Padilha along with his brother initiated agricultural commerce between the region and São Paulo.

The area received immigration and integrated the 4ª Colônia de Imigração Italiana (4th Colony of Italian Immigration). As a result, it includes people of Italian, Portuguese and Spanish descent.

The municipality Pinhal Grande was created under Law nº 9600 March 20, 1992.
