Christian nationalism is a form of religious nationalism that focuses on promoting the Christian views of its followers, in order to achieve prominence or dominance in political, cultural, and social life. In countries with a state church, Christian nationalists seek to preserve the status of a Christian state.

In Brazil, Christian nationalism, a result of a Catholic-Evangelical coalition, has a goal of curbing the influence of "moral relativism, social liberalism, alleged neo-Marxism in its various forms, and LBGTQ rights".

A 2024 Pew Research Center survey found that 13% of Brazilians self-identified as "religious nationalists".

The COVID-19 pandemic saw a rise in Christian nationalist activity with many groups using anti-lockdown sentiments to expand their reach to more people. The group Liberty Coalition Canada has garnered support from many elected politicians across Canada. In their founding documents, they argue that "it is only in Christianized nations that religious freedom has ever flourished". Their rallies have attracted the support of Alex Jones and Canada First, a spin-off of Nick Fuentes' group America First. Many of Liberty Coalition Canada's leaders are pastors who have racked up millions in potential fines for violating COVID protocols and in many cases express ultra-conservative views.

A 2024 Pew Research Center survey found that 3% of Canadians self-identified as "religious nationalists".

The small far-right and pro-Russian Power Belongs to the People (VKK) party has been described as Christian nationalist by Helsingin Sanomat. Sanan- ja uskonnonvapaus ry [fi] (Freedom of Speech and Religion Association), associated with MP and former chair of the Christian Democrats Päivi Räsänen, has also supported openly fascist candidates of Blue-and-Black Movement that seek to ban the LGBT movement and "non-native religions". The association also supports VKK and Freedom Alliance. The Blue-and-Black Movement itself is also inspired by the Christian fascist Patriotic People's Movement and its leader Tuukka Kuru [fi] is a member of the traditionalist Lutheran Mission Diocese. Aforementioned local far-right pro-Russian parties have recruited combatants for the Russian side in Ukraine, who have then after gone to the Russian Imperial Movement's training camps in St. Petersburg and become fighters in the Russo-Ukrainian War.

The Finnish Bible Belt of Ostrobothnia has been significantly shaped by the conservative Finnish Lutheran revival and Awakenism. The area was also the place of origin of the Finnish fascist movements Lapua Movement and Patriotic People's Movement, and revivalism was a dominant force among Finnish fascists and Nazis. Even in the modern day, the Revivalist Lutheran Evangelical Association of Finland [fi] chooses to ordain their priests in Russian Evangelical Lutheran Church of Ingria because of its strong opposition to the LGBT movement and women in ministry.

There has emerged a Finnish Christian nationalist media ecosystem. Neo-Nazi Nordic Resistance Movement has published Magneettimedia newspaper that Suomen Kuvalehti characterized as Christian nationalist. The newspaper and its distribution were funded by department store tycoon and holocaust denier Juha Kärkkäinen. In 2013 the newspaper was circulated to some 660,000 households. Theological magazine Vartija also defined as Christian nationalist the alt-tech website Oikea Media [fi], Patmos Mission Foundation [fi] and the television channels TV7 [fi] and AlfaTV [fi]. It further observes that "It has been noticeable that those on the extreme right, both religiously and politically, have found each other": there is an informal group of over 500 religious members of the far-right Finns Party.
