The Saale glaciation or Saale Glaciation, sometimes referred to as the Saalian glaciation, Saale cold period, Saale complex (Saale-Komplex) or Saale glacial stage, covers the middle of the three large glaciations in Northern Europe and the northern parts of Eastern Europe, Central Europe and Western Europe by the Scandinavian Inland Ice Sheet. It follows the Holstein interglacial and precedes the Eemian interglacial, spanning from around 400,000 years ago to 130,000 years ago. The Saalian covers multiple glacial cycles punctuated by interglacial periods. In its latter part it is coeval with the global Penultimate Glacial Period.

The Last Interglacial, also known as the Eemian among other names was the interglacial period which began about 130,000 years ago at the end of the Penultimate Glacial Period and ended about 115,000 years ago at the beginning of the Last Glacial Period. It corresponds to Marine Isotope Stage 5e. It was the second-to-latest interglacial period of the current Ice Age, the most recent being the Holocene which extends to the present day. During the Last Interglacial, the proportion of CO2 in the atmosphere was about 280 parts per million. The Last Interglacial was one of the warmest periods of the last 800,000 years, with temperatures comparable to and at times warmer than the contemporary Holocene interglacial, with the maximum sea level being up to 6 to 9 metres higher than at present, with global ice volume likely also being smaller than the Holocene interglacial.
