Vittorio Fossombroni (15 September 1754 – 13 April 1844) was an Italian statesman, mathematician, economist and a distinguished drainage engineer.

He obtained an official appointment in Tuscany in 1782, and twelve years later was entrusted by the grand duke with the direction of the works for the drainage of the marshy Valdichiana, one of the four valleys around Arezzo, on which subject he had published a treatise in 1789.

On the erection of the grand duchy into the ephemeral Kingdom of Etruria, under the queen-regent Maria Louise, he was, appointed president of the commission of finance.

[1] According to Luigi Villaris, writing in the Encyclopædia Britannica Eleventh Edition: "His administration, which was only terminated by his death, greatly contributed to promote the well-being of the country.

He was the real master of Tuscany, and the bases of his rule were equality of all subjects before the law, honesty in the administration of justice and toleration of opinion, but he totally neglected the moral improvement of the people.
