Ouro Verde do Oeste is a municipality in the state of Paraná, in the Southern Region of Brazil. It is one of the many small municipalities that make up the interior of Paraná, a state whose western areas were settled and organized as agricultural communities during the twentieth century.
Like other municipalities in Paraná, Ouro Verde do Oeste is administered as a local government unit with its own municipal authority, and it forms part of the state's system of cities and districts. Its name, which means "Green Gold of the West" in Portuguese, reflects the common practice in the region of naming places after local resources or geographic position.
Detailed information on the municipality's population, area, economy, and history is limited in the available source material, so only its status as a municipality within Paraná and its location in southern Brazil can be stated with confidence.
