The town's name derives from the Latin person's name "Travinus" and the addition of the suffix "-anus ", which denotes membership, " Land of Travinus". Probably, the name of the Roman centurion to whom the lands were assigned, as for their customs.

The numerous objects of the Roman era, found in the area, attest the colonization of the Empire and its permanent presence here. The first historical document which proves the existence of a settlement dates back to 1184, a time when this area was dominated by the Patriarchate of Aquileia, an institution founded in 1077 and continued until 1420, when it was conquered by the Venetians. The town also submitted the domain of the Count of Gorizia. The history of Trivignano was marked by long-standing struggle between the Venetian Serenissima Republic and the Habsburg Empire for dominance in the region of Friuli. The conflict came to an end only in the first half of the XVI century with the treaty of Worms, when the territories were assigned to the Republic of Venice until the stipulation of the Treaty of Campoformio, when it was ceded to Austria till the abolition of feudalism in 1866.
