Some historians believe that the name of the city was given by the Negros who lived in the region and belonged to a runaway slave colony called Campo Grande. This hypothesis is reinforced by the existence of a city with the same name in Cameroon, in Africa. Another interpretation for the name of the city is that it is of indigenous origin and means "river of dirty waters".
