The Dolmen du Bois de Galtier is a dolmen in Martiel in the Aveyron department in France.
The dolmen is located within the remains of its round hill, which was once around 20.0 m. In the west, instead of the usual end stone, it has a round paved chamber made of low-lying dry masonry measuring around 2.5 meters. It is possible that this chamber is the remainder of a modern shepherd's hut, many of which are found here in the woods. The dolmen, made of three preserved stones, stands in front of the round chamber as a kind of corridor and is about 3.55 meters long and 1.2 m wide inside. The bearing stones are 0.3 and 0.38 m thick.
