Le Clapier (French pronunciation: [lə klapje]; Occitan: Lo Clapièr) is a commune in the Aveyron department in southern France.

The edge of Larzac (also called the Western Guillhaumard) is made of large white limestone cliffs dating from the Bathonian age.

Also, the valley of the Sorgue close to Larzac reveals sediments dating as far back as the Cambrian Series 2.

In the center of the village, the Clapier castle is made of the remains of a medieval fort, probably built by the Hospitallers of Jerusalem.

Episcopal archives mention that the fort of Clapier was built for pilgrims on the Way of St. James to shelter them from wolves and brigands.
