Paranaiguara began in the 1930s when diamond prospectors came into the area. In 1950 the settlement became a district of Quirinópolis and in 1967 it got its emancipation with the present name. The name means "inhabitants of the great river" in Tupi-guarani. In 1976 the construction of the São Simão Dam and reservoir forced the evacuation of the old town, which was moved 15 kilometers away.
