Ferrante III Gonzaga (4 April 1618 – 11 January 1678), was a Duke of Guastalla.
He succeeded his father in 1632. In 1638 he sold all the minor napolitean fiefs and in 1640 also sold the Principality of Molfetta. He was invested as Knight of the Order of San Jago and Commendator of Villahermosa in 1639.

When Ferrante III died without surviving male heirs, the Duchy of Guastalla became officially a part of the Duchy of Milan, but was ruled by Ferdinando Carlo of Mantua (husband of the eldest surviving daughter) between 1678 and 1692. Due to Austrian intervention, the Duchy then passed to Vincenzo Gonzaga (husband of the second daughter).
