Bragny-sur-Saône (French pronunciation: [bʁaɲi syʁ son], literally Bragny on Saône) is a commune in the Saône-et-Loire department in the region of Bourgogne-Franche-Comté in eastern France.

From 530 to 450 or 440 BC there was considerable trade conducted in this area between the Hallstatt people and the Greeks. Mediterranean pottery, including amphorae from Massalia, as well as artefacts from Attica, and polychrome glass have all been found in large numbers here. Trade eased up for a while in the early 5th century BC but soon sprung back into life. Artefacts from northern Italy, as well as Golaseccan pottery were found from this time onwards, along with more Massiliot amphorae.

In August 1636, the soldiers of Matthias Gallas burned the village center, church, and part of the château. Rebuilding was needed, and it was the Count of Thiard who had most of it done since the population were too poor.

By 1690, most residents lived in small brick and mud houses, roofed with tiles or straw. They also usually slept in straw on the ground.

A mill has existed here since before 1243. Peasants of Bragny and surrounding villages would come to the mill and pay the owner to have their grains ground.

Pontus de Tyard, a famous owner of the mill, wrote letters detailing how the millers would cheat him by paying late, and also cheat the peasants by withholding flour.

In 1740, Jacques de Thiard began reconstruction of the mill.

The mayor of Bragny is Estelle Invernizzi.
