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.

Adonism is a Neopagan religion founded in 1925 by the German esotericist Franz Sättler, who often went by the pseudonym of Dr. Musalam. Although Sättler claimed that it was the continuation of an ancient pagan religion, it has been recognised by academics as being "instead the single-handed creation of a highly gifted and educated man", this figure being Sättler himself. Adonism is a polytheistic religion, revolving around a belief that there are five principal gods: Belus, Biltis, Adonis, Dido and Molchos. Adonis is the most prominent of these in the group's theology, being a benevolent figure that Sättler equated with the Christian figure of Satan. In contrast to Adonis, Molchos is believed by Adonists to be malevolent, and to be responsible for the enslavement of humanity through monotheistic religions such as Judaism, Christianity and Islam: the religion therefore has "a pronounced anti-Christian bias".

Armanism and Ariosophy are esoteric ideological systems that were pioneered by Guido von List and Jörg Lanz von Liebenfels respectively, in Austria between 1890 and 1930. The term 'Ariosophy', which means the wisdom of the Aryans, was first coined by Lanz von Liebenfels in 1915 and in the 1920s, it became the name of his doctrine. In research on the topic, such as Nicholas Goodrick-Clarke's book The Occult Roots of Nazism, the term 'Ariosophy' is generically used to describe the Aryan-esoteric theories of a subset of the 'Völkische Bewegung'. This broader use of the word is retrospective and it was not generally current among the esotericists themselves. List actually called his doctrine 'Armanism', while Lanz used the terms 'Theozoology' and 'Ario-Christianity' before the First World War.

The Odinist Community of Spain – Ásatrú, also known as European Odinist Circle, is a Germanic neopagan organisation in Spain, founded in 1981, for followers of the denomination of modern heathenism known as Odinism, and is also accepting of broader Ásatrú and Vanatrú neo-heathenism. The community bases its ideology on the Visigothic, Suevian and Vandalian Germanic heritage of modern Spain, Portugal and Occitania, dating to the 6th century. It was legally recognised as a religious institution by the Spanish government in 2007, and performed the first legal pagan wedding in mainland Spain since the Visigothic era, in Barcelona on 23 December 2007. In Albacete in 2009, COE completed the first temple to Odin believed to have been built in over 1,000 years. A less Odin-focused group split off in 2012 as the Ásatrú Lore Vanatrú Assembly (ALVA).

In Nazi Germany, Gottgläubig was a Nazi religious term for a form of non-denominationalism practised by those Germans who had officially left Christian churches but professed faith in some higher power or divine creator. Such people were called Gottgläubige, and the term for the overall movement was Gottgläubigkeit. The term denotes someone who still believes in God, although without having any institutional religious affiliation. The Nazis were not favourable towards religious institutions of their time, but rather sought to inculcate a new Nazi-friendly Positive Christianity, a belief in the God that was one's race-consciousness, and a variety of non-Christian systems of belief that defined "God" variously but always in a way that could be subsumed into the National Socialist ideology. In this way, they could reject atheism of any type within the NSDAP membership: Gottgläubigkeit was a kind of officially sanctioned unorganised religion somewhat equivalent to a "non-denominational Christian" in the United States. The 1943 Philosophical Dictionary defined gottgläubig as: "official designation for those who profess a specific kind of piety and morality, without being bound to a church denomination, whilst however also rejecting irreligion and godlessness." In the 1939 census, 3.5% of the German population identified as gottgläubig.

Heathenry as it is expressed in Canada is used as a universal term to describe a wide range of Germanic Neopaganism. Those who practice the religions or folk-ways of Ásatrú, Forn Sed, Odinism or Theodism are all considered part of a greater Heathen umbrella. In Canada, Heathenry takes a socially liberal standing in its philosophy. The exclusion of adherents on the basis of ethnic origin, sexual orientation, other group affiliation as well as other discriminatory factors is opposed by most Canadian Heathen groups, although there are, as in the United States a small number of racially minded groups that limit their membership to those of "Nordic ancestry".
Hof Ásatrúarfélagsins is a religious building under construction in Reykjavík, Iceland. When finished it will be used by the Heathen organization Ásatrúarfélagið for religious ceremonies, concerts and exhibitions. It is Iceland's first major hof to the Norse gods since the Viking Age. It is located on the southern slope of the hill Öskjuhlíð, close to Reykjavík University. The project has been under development since 2005, but has been delayed several times because of the 2008–2011 Icelandic financial crisis and problems with the design. It has been under construction since 2015.

Project Megiddo was a report researched and written by the United States' Federal Bureau of Investigation under Director Louis Freeh. Released on October 20, 1999, the report named followers of white supremacy, Christian Identity, the American militia movement, Black Hebrew Israelites, and apocalyptic cults as potential terrorists who might become violent in reaction to the new millennium.
There is some evidence that, in addition to being a writing system, runes historically served purposes of magic. This is the case from earliest epigraphic evidence of the Roman to Germanic Iron Age, with non-linguistic inscriptions and the alu word. An erilaz appears to have been a person versed in runes, including their magic applications.

Neopaganism in Scandinavia is almost exclusively dominated by Germanic Heathenism, in forms and groups reviving Norse paganism. These are generally split into two streams characterised by a different approach to folk and folklore: Ásatrú, a movement that been associated with the most innovative and Edda-based approaches within Heathenry, and Forn Siðr, Forn Sed or Nordisk Sed, a movement marked by being generally more traditionalist, ethnic-focused and folklore-rooted, characterised by a worldview which its proponents call folketro. Forn Siðr may also be a term for Scandinavian Heathenry in general. Vanatrú defines the religion of those individuals or groups in which the worship of the Vanir dominates.
