The origin of Ouvidor dates to 1922, when the train station on the Estrada de Ferro Goiás was inaugurated. The settlement began to grow with farmers moving into the region and it belonged to Catalão. The first name was Catuaba, the name of a local plant. With the increase in population the town became a district in 1948 and finally a municipality in 1953. The name was changed to Ouvidor, because of the small river that passes nearby.
