Religious affiliations can affect the electability of the presidents of the United States and shape their stances on policy matters and their visions of society and also how they want to lead it. While no president has ever openly identified as an atheist, Thomas Jefferson, Abraham Lincoln, and William Howard Taft were speculated to be atheists by their opponents during political campaigns; in addition, a survey during the presidency of Donald Trump showed that 63% of Americans did not believe he was religious, despite his professed Christian affiliation. Conspiracy theorists also falsely circulated rumors that Barack Obama was a Muslim during his 2004 Senate campaign and later time as President. Conversely, other presidents, such as Jimmy Carter, used their faith as a defining aspect of their campaigns and tenure in office.
Religion in the United States began with the religions and spiritual practices of Native Americans. Later, religion also played a role in the founding of some colonies, as many colonists, such as the Puritans, came to escape religious persecution. Historians debate how much influence religion, specifically Christianity and more specifically Protestantism, had on the American Revolution. Many of the Founding Fathers were active in a local Protestant church; some of them had deist sentiments, such as Thomas Jefferson, Benjamin Franklin, and George Washington. Some researchers and authors have referred to the United States as a "Protestant nation" or "founded on Protestant principles," specifically emphasizing its Calvinist heritage. Others stress the secular character of the American Revolution and note the secular character of the nation's founding documents.
Religion in Canada encompasses a wide range of beliefs and customs that historically has been dominated by Christianity. The constitution of Canada refers to 'God', however Canada has no official church and the government is officially committed to religious pluralism. Freedom of religion in Canada is a constitutionally protected right, allowing individuals to assemble and worship without limitation or interference. Rates of religious adherence have steadily decreased since the 1960s. After having once been central and integral to Canadian culture and daily life, Canada has become a post-Christian state. Although the majority of Canadians consider religion to be unimportant in their daily lives, they still believe in God. The practice of religion is generally considered a private matter throughout society and the state.
The mainline Protestant churches are a group of Protestant denominations in the United States and Canada largely of the theologically liberal or theologically progressive persuasion that contrast in history and practice with the largely theologically conservative evangelical, fundamentalist, charismatic, confessional, Confessing Movement, historically Black church, and Global South Protestant denominations and congregations. Some make a distinction between "mainline" and "oldline", with the former referring only to denominational ties and the latter referring to church lineage, prestige and influence. However, this distinction has largely been lost to history and the terms are now nearly synonymous.

Religion in the United States is remarkable in its high adherence level compared to other developed countries. The First Amendment to the country's Constitution prevents the government from having any authority in religion, and guarantees the free exercise of religion. Many faiths have flourished in the United States, including imports spanning the country's multicultural heritage as well as those founded within the country, and have led the United States to become the most religiously diverse country in the world.
