George Emmanuel Mylonas was a Greek archaeologist of ancient Greece and Aegean prehistory. He excavated widely, particularly at Olynthus, Eleusis and Mycenae, where he made the first archaeological study and publication of Grave Circle B, the earliest known monumentalized burials at the site.

Grave Circle B in Mycenae is a 17th–16th century BCE royal cemetery situated outside the late Bronze Age citadel of Mycenae, southern Greece. This burial complex was constructed outside the fortification walls of Mycenae and together with Grave Circle A represent one of the major characteristics of the early phase of the Mycenaean civilization.
