Sauveterre-la-Lémance (French pronunciation: [sovtɛʁ la lemɑ̃s]; Occitan: Salvatèrra de Lemança) is a commune in the Lot-et-Garonne department in south-western France.

It was built at the end of the thirteenth century by Edward I of England in a strategic position between Périgord and Agen.

SauveTerre Musée de Préhistoire is a museum that exhibits collections from archaeological digs in the Lémance valley, including part of the collection of L. Coulonges, a self-taught archaeologist who undertook excavations in the Lémance valley in the 1920s.

In 1923, Laurence Coulonges discovered remains of a prehistoric culture between the Paleolithic and Neolithic period, somewhere between 7,000-9,500 years old.

The current museum was inaugurated in 1994, particularly devoted to the Mesolithic period, in which men gradually passed from a society of hunter-gatherers to a way of life of producers and farmers.
