Donald Trump was raised in the Presbyterian faith, which is a branch of Protestant Christianity, due to his Scottish-born mother's religious background. For much of his adult life, including during his 2016 presidential campaign, he publicly identified as Presbyterian. However, in October 2020, Trump stated that he no longer identified as Presbyterian and now considers himself a non-denominational Christian, aligning with a broader and less specific segment of Protestantism

. Despite his professed Christian affiliation, surveys during his presidency indicated that a significant portion of Americans questioned the depth of his religious commitment. Nevertheless, Trump has consistently appealed to conservative Christian groups, especially evangelical Protestants, and has had a close association with evangelical minister Paula White, who served as his spiritual advisor and delivered the invocation at his first inauguration

. In summary, Donald Trump identifies as a non-denominational Christian with roots in the Presbyterian tradition within Protestant Christianity
