Saintonge (French pronunciation: [sɛ̃tɔ̃ʒ]) is a small region and historical province on the Atlantic coast of France within the département Charente-Maritime, west and south of Charente in the administrative region of Poitou-Charentes. It derives its name from the ancient Gallic tribe of the Santones who lived in this area, around the current city of Saintes.

The Saintonge was the center of the French Huguenots. Today, the region is famous for its production of the grapes that are used to produce cognac and Pineau des Charentes.

It was the birthplace of the explorer Jean Allefonsce and Samuel de Champlain who founded Quebec.

Saintongeais (patouê saintonjhouê, jhabrail) is spoken in the former provinces of Saintonge, Aunis, and Angoumois

This area is also famous for its widely exported medieval pottery, shards of which are found in large quantities on medieval excavations throughout Ireland and other European countries. These shards are from vessels made and exported as a by-product of the Bordeaux wine trade (Deroeux and Dufournier, 1991). They consist of an off-white micaceous fabric with moderate amounts of quartz and sparse inclusions of haematite. They are glazed on the external surface only, with a clear lead glaze. In Saintonge Green wares the addition of copper filings produces a mottled mid-green colouring. Many forms of Saintonge wares were produced, including Saintonge Polychrome, Saintonge Green, and in some cases unglazed wares.
