The Boutouiller dolmen (also called Dolmen de Kerivin or Dolmen de Keranguez) is located in Saint-Pol-de-Léon in the Finistère department in Brittany in France.

The T-shaped Allée couverte is a good example of a gallery grave with side access or a dolmen à couloir, but today it is overgrown and surrounded by rubbish and is therefore difficult to see.
