Entrance grave is a term given by archaeologists to a type of megalithic chamber tomb found in parts of Atlantic Europe, dating the early to middle Bronze Age.

Tombs of this type are covered with a round earth mound and contain a single chamber where the entrance area merges with the burial area itself, simply through a slight change in the alignment of the stone slab walls. They are also known as undifferentiated passage graves.

Entrance graves are found in Southern Spain and all along the Atlantic coast to Brittany. They are also present in southern Ireland, the Isles of Scilly and Cornwall.

An example is the Scillonian entrance grave group.
