Portogruaro (Venetian: Porto, Friulian: Puart) is a town and comune in the Metropolitan City of Venice, Veneto, northern Italy. The city is the centre of a district, made up of 11 comuni, which form the Venezia Orientale with the San Donà di Piave district.
Portogruaro was officially founded in 1140, when the Archbishop of Concordia, Gervinus, gave a group of fishermen (Giovanni Venerio, Arpone, Bertaldo, Borigoio, Enrico Mosca, Giovanni Salimbene) the right to settle there and build a river port. A castle had existed on the site as early as the 10th century. In 1420, after centuries under Patria del Friuli, was conquered by the Republic of Venice. According to Bertolini the town's foundation could be coeval to the Concordia Sagittaria's one. Under the Venetians the town retained some autonomy and was able to expand economically up until the economic decline of Venice from the 17th century onwards.
Following the upheavals of the Napoleonic Wars, Portogruaro was incorporated into the Austrian Empire in 1815. Apart from a brief uprising in 1848 Portogruaro remained under Austrian control until 1866 when it entered the newly unified Kingdom of Italy. Since that time the population of Portogruaro has grown from under 10,000 to around 25,000.
The Roman and medieval city of Concordia Sagittaria was located nearby.
A former large phosphates producer is now closed. The Camuffo Boatyard, founded in 1438, is one of the oldest industries in the world.
The local football club is called Calcio Portogruaro Summaga, founded in 1990, and plays in the third Italian league (Lega Pro).
