Mycenaean Greece (or the Mycenaean civilization) was the last phase of the Bronze Age in Ancient Greece, spanning the period from approximately 1750 to 1050 BC. It represents the first advanced and distinctively Greek civilization in mainland Greece with its palatial states, urban organization, works of art, and writing system. The Mycenaeans were mainland Greek peoples who were likely stimulated by their contact with insular Minoan Crete and other Mediterranean cultures to develop a more sophisticated sociopolitical culture of their own. The most prominent site was Mycenae, after which the culture of this era is named. Other centers of power that emerged included Pylos, Tiryns, Midea in the Peloponnese, Orchomenos, Thebes, Athens in Central Greece and Iolcos in Thessaly. Mycenaean settlements also appeared in Epirus, Macedonia, on islands in the Aegean Sea, on the south-west coast of Asia Minor, Cyprus, while Mycenaean-influenced settlements appeared in the Levant, and Italy.

The Mycenaean Greeks introduced several innovations in the fields of engineering, architecture and military infrastructure, while trade over vast areas of the Mediterranean was essential for the Mycenaean economy. Their syllabic script, the Linear B, offers the first written records of the Indo-European Greek language, and their religion already included several deities that can also be found in the Olympic Pantheon. Mycenaean Greece was dominated by a warrior elite society and consisted of a network of palace-centered states that developed rigid hierarchical, political, social and economic systems. At the head of this society was the king, known as a wanax.

Mycenaean Greece perished with the collapse of Bronze Age culture in the eastern Mediterranean, to be followed by the Greek Dark Ages, a recordless transitional period leading to Archaic Greece where significant shifts occurred from palace-centralized to de-centralized forms of socio-economic organization (including the extensive use of iron). Various theories have been proposed for the end of this civilization, among them the Dorian invasion or activities connected to the "Sea Peoples". Additional theories such as natural disasters and climatic changes have also been suggested. The Mycenaean period became the historical setting of much ancient Greek literature and mythology, including the Trojan Epic Cycle.
