The Beaumer Dolmen (also called Er Mané) is located east of Carnac in the Morbihan department in Brittany in France.

The Neolithic dolmen stands at the entrance to a campsite. It consists of four supporting stones on which a ceiling plate lies. The monument was damaged at an unknown time in an attempt to destroy it, as evidenced by traces on four stones.

The dolmen has been classified as a Monument Historique since 1929.
