The Tomb of Clytemnestra was a Mycenaean tholos type tomb built in c. 1250 BC. A number of architectural features such as the semi-column were largely adopted by later classical monuments of the first millennium BC, both in the Greek and Latin world. The Tomb of Clytemnestra with its imposing façade is together with the Treasury of Atreus the most monumental tomb of that type.

The tomb is named after Clytemnestra, the wife of king Agamemnon, mythical ruler of Mycenae and leader of the Greeks in the Trojan War. However, it has been also suggested by modern scholars that this might have been Agamemnon's tomb or even that the tomb was never occupied due to the destruction of Mycenae which occurred during that time.
