The area was attested in the form castro barro in the 7th century and Barri villa in 932.

Bar comes from a Gallic word meaning "summit" and is perhaps even older (pre-Gallic).

Bar-sur-Aube appears as Bar sur Aube on the 1750 Cassini Map and the same on the 1790 version.

The existence of Bar-sur-Aube goes back to ancient times. There are remains of an oppidum from the Iron Age. A coin with the image of a horse in the name of Togirix (Chief of the Lingones) was discovered on the Sainte Germaine hill.

In Roman times the town appeared on the Tabula Peutingeriana under the name of Segessera. Some remains from the 1st to the 4th century including villas have been discovered in the town and surrounding areas. Segessera seemed to have existed from the Roman period to the first Lyonnais in the territory of the Lingones.

The city was devastated by Attila. After the division of the kingdom of Clovis by his son the town became part of Austrasia.

Under Charles the Bald several varieties of coins were issued with the name of the city on the reverse. During the period of the Counts of Champagne the town was of great importance with the Champagne fairs where merchants from Flanders and Italy traded Oriental spices and silk for textiles and raw materials from the north of Europe in mid-February and mid-April. The town was then joined to the crown of France. In 1318 Philip V the Tall sold the town to Jacques de Croÿ, residents bought it themselves to ensure that the king could no longer sell or alienate the lands.

When Charles V besieged Saint-Dizier the inhabitants of nearby villages came under his protection. The town suffered a long plague in 1636 which led to the end of the fair. In 1862 the fortifications were demolished and the boulevard du tour put in their place.

The French Revolution was well received in the commune and the convents disappeared. It became the chief town of the district from 1790 to 1800.

The city and surrounding area was the scene of the Battle of Bar-sur-Aube towards the end of the Napoleonic era on 27 February 1814.

In 1911 the Champagne riots of the Aube winegrowers and the Marnais traders to keep the vineyards in the Appellation d'origine contrôlée of "Champagne".
