Chatenet (French pronunciation: [ʃatnɛ]) is a commune in the Charente-Maritime in the department in the Nouvelle-Aquitaine region in southwestern France.

Chatenet is a small commune situated between the market town of Montendre and the large village of Chevanceaux.

It is principally a farming community; however in recent years tourism has become important.

The location of Chatenet in the southern tip of the Charente Maritime provides the area with a warm climate.

The Seugne flows north-northwestward through the middle of the commune and forms part of its southern and northern borders.
