Taillebourg (French pronunciation: [tajbuʁ]) is a commune in the Charente-Maritime department in southwestern France.

It is built on a rock, overlooking the river Charente, 9 km downstream from Saintes.

The place was first mentioned as terra Talleburgi in 1267.

It was the site of three battles that bear its name: Battle of Taillebourg, on account of its strategically important position as a river crossing.

The ancient bridge over the Charente has since been destroyed but there is a long causeway, which spans the surrounding marshes and serves to keep the road open, even during times of flooding.
