At the beginning of the 16th century, there were only indigenous lands in the region, one of which was the CAPOCU village, whose lands belonged to the government of the 5th District of São Paulo. In 1800, next to the CAPOCU farm, another farm called RIO GRANDE, or GRANDE RIO, because it developed on the banks of the Iguaçu River.

These two villages, originated by the two farms, became known as Fazenda Rio Grande, which, together with other towns in this region, on July 25, 1960, were dismembered from São José dos Pinhais, forming the Municipality of Mandirituba. In 1981, through Law 7521, published in the Official State Agency Nº 1.171, on November 17, 1981, signed by the then Governor Ney Braga, Fazenda Rio Grande became the Administrative District of the Municipality of Mandirituba. The emancipation of Fazenda Rio Grande is due to a specific socioeconomic context, which is linked to the growth of Greater Curitiba at the end of the 70s.

From 1975 onwards, with almost eradicating coffee production in the Northern Region of Paraná, there was a great movement of rural exodus in the State, attracting many people to the Metropolitan Region of Curitiba. The Municipality of Fazenda Rio Grande began to become a reality on September 15, 1989, through Bill No. 229/89, authored by State Deputy Aníbal Khury.

On January 26, 1990, through State Law nº 9.213, sanctioned by the then Governor Álvaro Fernandes Dias, in the premises of Churrascaria 22, in the presence of more than three thousand witnesses, the Municipality of Fazenda Rio Grande was created. Today Fazenda Rio Grande is characterized by being one of the fastest-growing Brazilian municipalities, with a population growth of around 10% per year, being the seat of the Comarca since 1999. The installation of the Municipality took place on April 12, 1991, at 1:30 pm at the Forum of the District of São José dos Pinhais, by the then Judge of Law Dr. Raul Luiz Gutmann, published in the Diário da Justiça through decree nº 360.
