Marine Isotope Stage 11 (MIS 11) is a specific period in Earth's climatic history that occurred between approximately 400,000 and 420,000 years ago, during the Late Pleistocene epoch. It is characterized by a relatively warm interglacial period, which is part of a series of alternating glacial and interglacial stages documented in the paleoclimatic record.
