Universalism is a religious, theological, and philosophical concept with universal application or applicability. Universalist doctrines consider all people in their formation.

In terms of religion, in a broad sense, universalism claims that religion is a universal human quality. This can be contrasted with non-universalist religions. Religion in this context is defined as "a set of beliefs concerning the cause, nature, and purpose of the universe, especially when considered as the creation of a superhuman agency or agencies, usually involving devotional and ritual observances, and often containing a moral code governing the conduct of human affairs."
