The Danube glaciation, Donau glaciation () or the Danube Glacial (Donau-Glazial) was named by Barthel Eberl in 1930 after the River Danube. It did not appear in the traditional, quadripartite ice age schema of the Alps by Albrecht Penck. The Danube was the oldest glaciation in the Alps for which there was evidence outside of the Iller-Lech region. Danube Stage was thought to be preceded by the Biber-Danube interglacial and followed by the Danube-Günz interglacial.
