La Marche is a cave and archaeological site located in Lussac-les-Châteaux, a commune in the department of Vienne, western France. It is an archaeological site that has engendered much debate that has not been resolved to date. The carved etchings discovered there in 1937 show detailed depictions of humans and animals that may be 15,000 years old. The cave paintings at this site, however, are controversial and many doubt their authenticity.

When French scientist Léon Péricard excavated La Marche between 1937 and 1942, he catalogued more than 1,500 slabs of limestone that had been placed carefully on the floor.

In the past two decades an extensive inventory of the cave has been taken. 1,512 pieces have been found and numbered, 386 of which were deemed as compositional entities. The content of these etchings include animals, such as lions and bears, along with 155 depictions of humans, clad in robes and boots, each with their own well-defined faces.
