The Anglian Stage is the name used in the British Isles for a middle Pleistocene glaciation.

[6] The Anglian was the most extreme glaciation during the last two million years.

[7] In the south-east of England it diverted the River Thames from its old course through the Vale of St Albans south to its present position.

The stage names "Kansan", "Yarmouth", "Nebraskan" and "Aftonian" were later abandoned by North American Quaternary geologists and merged into the Pre-Illinoian stage.

[9][10] The Anglian Stage is now correlated with the period of time which includes the Pre-Illinoian B glaciation of North America.
