The Sturtian glaciation was a glaciation during the Cryogenian Period, when the Earth experienced repeated large-scale glaciations. The Sturtian glaciation was the longest one, lasting around 60 million years, from 717–660 Ma.

According to Eyles and Young, "Glaciogenic rocks figure prominently in the Neoproterozoic stratigraphy of southeastern Australia and the northern Canadian Cordillera. The Sturtian glaciogenic succession (c. 740 Ma) unconformably overlies rocks of the Burra Group." The Sturtian succession includes two major diamictite-mudstone sequences, which represent glacial advance and retreat cycles. It is stratigraphically correlated with the Rapitan Group of North America.

The Sturtian is named after the Sturt River Gorge, near Bellevue Heights, South Australia.
