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

Archiac is located in the south of the department of Charente Maritime in the historic region of Saintonge some 20 km south of Cognac, 15 km north-west of Barbezieux-Saint-Hilaire and 15 km north-east of Jonzac. The village has the status of a town and is located at the intersection of two main highways: the D699 from Arthenac in the south-west to Ambleville in the north-east; and the D731 from Cierzac in the north-west which continues south-east from the village. The north-eastern border of the commune is also the border between Charente-Maritime and Charente departments. Other access roads include the D149 which is a short-cut connection between the D699 and the D733 west of the village and the D152 which goes south from the village to Saint-Maigrin. There are also the hamlets of La Grue and Saint-Pierre north-east of the village. Apart from some wooded areas near the village the commune is entirely farmland.

• In the reign of Charlemagne Archiac was the seat of a viguerie.
• Upon the removal of Emma, the wife of the lord of Cognac, by the lord of Barbezieux in the 11th century, the Lord of Archiac gave them asylum: the castle was attacked, taken, and burnt.
• In 1219 the Lord of Archiac was Guillaume d'Archiac. During the Hundred Years War the castle was taken and retaken then became a den of Anglo-Gascon thieves before being taken and demolished.
• In 1609 the Barony of Archiac was raised to a marquisate.
• It was forbidden for the Protestant ministers Jacques Fountaines and Jean Hoummeau to preach and the temple was demolished in 1673.
