The Dorian invasion is a concept devised by historians of Ancient Greece to explain the replacement of pre-classical dialects and traditions in Southern Greece by the ones that prevailed in Classical Greece. The latter were named "Dorian" by the ancient Greek writers, after the Dorians, the historical population that spoke them.

Greek legend asserts that the Dorians took possession of the Peloponnese in an event called the Return of the Heracleidae (Ancient Greek: Ἐπιστροφὴ τῶν Ἡρακλειδῶν). Nineteenth-century Classical scholars saw in the legend a possibly real event they termed the Dorian invasion. The meaning of the concept has changed several times, as historians, philologists and archaeologists used it in attempts to explain the cultural discontinuities expressed in the data of their fields. The pattern of arrival of Dorian culture on certain islands in the Mediterranean, such as Crete, is also not well understood. The Dorians colonised a number of sites on Crete such as Lato.^[1]

Despite nearly 200 years of investigation, the historicity of a mass migration of Dorians into Greece has never been established, and the origin of the Dorians remains unknown. Firm archeological evidence of such an invasion has not been established. Nonetheless, the pervasiveness of the Dorians in literature means that most historians do not reject the theory.^[2] Some have linked them or their victims with the emergence of the equally mysterious Sea Peoples during the Late Bronze Age collapse. The meaning of the phrase "Dorian invasion" as an explanation for the cultural and economic breakdown after the Mycenaean period and into the Greek Dark Ages has become to some degree amorphous.
