Kamouraska (French pronunciation: [kamuʁaska] ⓘ) is a regional county municipality in eastern Quebec, Canada.

The regional county municipality seat is Saint-Pascal, but the largest town is La Pocatière.

Factories in the region produce metal products and public transportation equipment.

One of the people instrumental in settling and developing this area was Pascal Taché, an early seigneur.

The name "Kamouraska" comes from an Algonquin word meaning "where rushes grow at the water's edge".
