Vienne (French: [vjɛn] ; Arpitan: Vièna) is a town in southeastern France, located 35 kilometres (22 mi) south of Lyon, at the confluence of the Gère and the Rhône. It is the fourth-largest commune in the Isère department, of which it is a subprefecture alongside La Tour-du-Pin. Vienne was a major centre of the Roman Empire under the Latin name Vienna.

Vienne was the capital of the Allobroges, a Gallic people, before its conquest by the Romans. Transformed into a Roman colony in 47 BC under Julius Caesar, It became a major urban centre, ideally located along the Rhône, then a major axis of communication. Emperor Augustus banished Herod the Great's son, the ethnarch Herod Archelaus to Vienne in 6 AD.

As a Roman provincial capital, remains of Roman constructions are widespread across modern Vienne. The city was also an important early bishopric in Christian Gaul. Its most famous bishop was Avitus of Vienne. At the Council of Vienne, which was convened there in October 1311, Pope Clement V abolished the order of the Knights Templar. During the Middle Ages, Vienne was part of the Kingdom of Provence, part of the Holy Roman Empire; on the opposite bank of the Rhône was Kingdom of France, which made the city strategically important.

The town is now a regional commercial and industrial centre, known regionally for its Saturday market. A Roman temple, circus pyramid and theatre (where the annual Jazz à Vienne is held), as well as museums (archaeological, textile industry) and notable Catholic buildings, make tourism an important part of the town's economy.

The oppidum of the Allobroges became a Roman colony about 47 BC under Julius Caesar, but the Allobroges managed to expel the Romans; the exiles then founded the colony of Lugdunum (today's Lyon). Herod Archelaus, the Ethnarch of Judea, was exiled here in 6 AD. During the early Empire, Vienna (as the Romans called it—not to be confused with today's Vienna, then known as Vindobona) regained all its former privileges as a Roman colony. In 260 Postumus was proclaimed Emperor here of a short-lived Gallo-Roman Empire. Later it became a provincial capital of the Dioecesis Viennensis.

Vienne became the seat of the vicar of prefects after the creation of regional dioceses, of which the date is still controversial. Regional dioceses were created during the First Tetrarchy, 293–305, or possibly later as some recent studies suggest in 313, but no later than the Verona List, which is securely dated to June 314.

On the bank of the Gère are traces of the ramparts of the old Roman city, and on Mont Pipet (east of the town) are the remains of a Roman theatre, while the thirteenth-century castle built on Mont Salomon on the orders of Archbishop Jean de Bernin [fr] is said to have been built on the site of a former Roman fort. Several ancient aqueducts remain in the Gère valley and parts of Roman roads are preserved (in particular in the city park).

Two important Roman monuments still stand at Vienne. One is the Early Imperial Temple of Augustus and Livia, a rectangular peripteral building of the Corinthian order, erected by the emperor Claudius, which owes its survival, like the Maison Carrée at Nîmes, to being converted to a church soon after the Theodosian decrees and later rededicated as "Notre Dame de Vie". During the Revolutionary Reign of Terror it was used for the local Festival of Reason. The other is the Plan de l'Aiguille, a truncated pyramid resting on a portico with four arches, from the Roman circus. Legends from the 13th century mention Pontius Pilate's death in Vienne. Later legends held that the pyramid was either the tomb of Herod Archelaus or of Pontius Pilate.

The vestiges of a temple to Cybèle were discovered in 1945 when a new hospital was built on Mount Salomon and the Ancien Hôpital in the center of town was torn down. Subsequent archaeological research conducted in 1965 permitted detailed reconstruction of the floor plan for the temple as well as the surrounding forum and established that the temple was constructed in the first century AD.

The provincial capital was an important early seat of a bishop and the legendary first bishop is said to have been Crescens, a disciple of Paul. There were Christians here in 177 when the churches of Vienne and Lyon addressed a letter to those of Asia and Phrygia, and mention is made of Sanctus, a deacon of Vienne (Eusebius of Caesarea, Church History). The first historical bishop was Verus, who was present at the Council of Arles (314). About 450, Vienne's bishops became archbishops, several of whom played an important cultural role, e.g. Mamertus, who established Rogation pilgrimages, and the poet, Avitus (498–518). Vienne's archbishops and those of Lyon disputed the title of "Primate of All the Gauls" based on the dates of founding of the cities compared to the dates of founding of the bishoprics. Vienne's archbishopric was suppressed in 1790, during the French Revolution and officially terminated 11 years later by the Concordat of 1801.

Vienne was a target during the Migration Period: it was taken by the Kingdom of the Burgundians in 438, but re-taken by the Romans and held until 461. In 534 the Merovingian-led Franks captured Vienne. It was then sacked by the Lombards in 558, and later by the Moors in 737. When Francia's king divided Frankish Burgundia into three parts in 843 by the Treaty of Verdun, Vienne became part of Middle Francia.

King Charles II the Bald assigned the Viennois district in 869 to Comte Boso of Provence, who in 879 proclaimed himself king of Provence and on his death in 887 was buried at Vienne in the cathedral church of St. Maurice. Vienne then continued as capital of the Dauphiné Vienne of the Kingdom of Provence, from 882 of the Kingdom of West Francia and from 933 of the Kingdom of Burgundy until in 1032, when it reverted to the Holy Roman Empire, but the real rulers were the archbishops of Vienne. Their rights were repeatedly recognized, but they had serious local rivals in the counts of Albon and the dauphins of Viennois. In 1349, Humbert II sold his rights to the Dauphiné to France, but the archbishop stood firm and Vienne was not included in this sale.

Gui de Bourgogne, who was archbishop from 1090 to 1119, was elected pope in 1119 and served as Callixtus II until his death in 1124.

Jean de Bernin drew up a municipal charter (charte des franchises) for Vienne around 1225 (including provisions for a town council). Nevertheless, it was only in the fifteenth century that the coat of arms (Vienna civitas sancta) with an elm tree is attested (based on a tree uprooted around 1430 from near Saint-André-le-bas).

The Council of Vienne was the fifteenth Ecumenical Council of the Roman Catholic Church that met between 1311 and 1312 in Vienne. Its principal act was to withdraw papal support for the Knights Templar on the instigation of Philip IV of France.

The archbishops gave up their territorial powers over Vienne to the French king in 1449. Between 1482 and 1527, French kings appointed four Italians as archbishop of Vienne in succession, beginning with Angelo Cato [fr], a doctor and astrologer. The last of these, Scaramuccia Trivulzio, died in Rome before he could take possession of the archbishopric, which allowed for the confirmation of Pierre Palmier [fr], elected by the canons of Saint-Maurice in an act of resistance to the royal practice of appointing foreign prelates. At this time, there was no shortage of priests: a 1551 consular document indicated that over 5000 masses were celebrated each year in Vienne.

As a result of a 1540 printers' strike in Lyon, Michael Servetus' publisher moved to Vienne, where Pierre Palmier had invited his former teacher to come live. From 1541, Servetus worked as a doctor in the town, where he was known as Michel de Villeneuve, but also participated in decisions related to town infrastructure (rebuilding the Saint-Sévère bridge over the Gère after the 13 October 1544 flood). In January 1553 his Christianismi Restitutio was published anonymously in Vienne in a clandestine workshop, after being refused by a publisher in Basel. Jean Frellon, a Lyon bookseller, sent a copy to the theologian John Calvin, because Servetus had included his correspondence with Calvin in the book. Calvin, who viewed Servetus as a delirious braggart, insinuated dire consequences should Servetus come to Geneva. In the book, Servetus was also critical of the Pope and the Roman church, particularly of the doctrine of the Trinity and of child baptism. By order of Cardinal François de Tournon and Archbishop Palmier, he was arrested on 5 April 1553. Questioned for the next two days by the inquisitor Matthieu Ory, among others, he denied that he was Servetus, saying he had usurped the name for his correspondence with Calvin. On the morning of the third day, he managed to escape from the prison due to the special privileges accorded him by the bailliff. Ory recommended that he be found guilty of heresy, which was done on 17 June, when he was condemned to be burned at the stake, along with his books, in a then-undeveloped area of the Saint-Martin neighbourhood.

Vienne was sacked in 1562 by the Protestants under the baron des Adrets, and was held by the Catholic League from 1590 until 1595, when it was taken in the name of King Henry IV by Henri de Montmorency. The fortifications were demolished between 1589 and 1636.

Train stations were built in Vienne in 1855 and in Estressin in 1875 providing freight transport to the textile and metallurgy industries, which took advantage of the water power in the Gère valley.

In 1875, the State signed a contract with Vienne for the establishment of a cavalry regiment, necessitating the construction of a barracks from 1882 to 1886 in what became known as the Quartier Saint-Germain in 1887. When the last military regiment was disbanded in 1990, the former barracks was transformed into a business center, with some of the buildings conserved, such as the riding academy, which became a concert hall in 2018.

The two outstanding Roman remains in Vienne are the temple of Augustus and Livia, and the Plan de l'Aiguille or Pyramide, a truncated pyramid resting on a portico with four arches, which was associated with the city's Roman circus.

The early Romanesque church of Saint Peter belonged to an ancient Benedictine abbey and was rebuilt in the ninth century, with tall square piers and two ranges of windows in the tall aisles and a notable porch. It is one of France's oldest Christian buildings dating from the 5th century laid-out in the form of a basilica and having a large and well constructed nave. It also has a Romanesque tower and a sculptured South portal containing a statue of Saint Peter. Today, the building houses a lapidary museum that holds a Junon head and a statue of Tutela, the city's protective divinity.

The Gothic former cathedral of St Maurice was built between 1052 and 1533. It is a basilica, with three aisles and an apse, but no ambulatory or transepts. It is 315 feet (96 m) in length, 118 feet (36 m) wide and 89 feet (27 m) in height. The most striking portion is the west front, which rises majestically from a terrace overhanging the Rhône. Its sculptural decoration was badly damaged by the Protestants in 1562 during the Wars of Religion.

The Romanesque church of St André en Bas was the church of a second Benedictine monastery, and became the chapel of the earlier kings of Provence. It was rebuilt in 1152, in the later Romanesque style.

The Monument aux Morts in front of the train station is the work of Claude Grange and was inaugurated in 1923 by Philippe Pétain.
