Thomas I (1239-1296) was the fourth marquess of Saluzzo from 1244 to his death. He succeeded his father Manfred III. Under the reign of Thomas, Saluzzo blossomed, achieving a greatness which had eluded his ancestors. He crafted a state the borders of which remained unchanged for over two centuries. He extended the march to include Carmagnola. He was often at odds with Asti and he was a prime enemy of the Charles of Anjou and his Italian pretentions. During his tenure, he made Saluzzo a free city, giving it a podestà to govern in his name. He defended his castles and roccaforti (strongholds) vigorously and built many new ones in the cities.
He married Luisa of Ceva.
He was succeeded by his son Manfred. Thomas also had a daughter, Alice of Saluzzo, who married Richard Fitzalan, 8th Earl of Arundel.
