Heathenry in the United Kingdom consists of a variety of modern pagan movements attempting to revive pre-Christian Germanic religiosities, such as that practised in the British Isles by Anglo-Saxon and Nordic peoples prior to Christianisation.

Heathenry, also termed Heathenism, contemporary Germanic Paganism, or Germanic Neopaganism, is a modern Pagan religion. Scholars of religious studies classify it as a new religious movement. Developed in Europe during the early 20th century, its practitioners model it on the pre-Christian religions adhered to by the Germanic peoples of the Iron Age and Early Middle Ages. In an attempt to reconstruct these past belief systems, Heathenry uses surviving historical, archaeological, and folkloric evidence as a basis, although approaches to this material vary considerably.
