Secularity (adjective form secular) is the state of being separate from religion.

For instance, eating and bathing may be regarded as examples of secular activities, because there may not be anything inherently religious about them. Nevertheless, both eating and bathing are regarded as sacraments in some religious traditions, and therefore would be religious activities in those world views. Saying a prayer derived from religious text or doctrine, worshipping through the context of a religion, and attending a religious school are examples of religious (non-secular) activities. Prayer and meditation are not necessarily non-secular, since the concept of spirituality and higher consciousness are not married solely to any religion but are practiced and arose independently across a continuum of cultures. However, it can be argued that these practices have arisen as a result of religious (non-secular) influence.

Most businesses and corporations, and some governments, are secular organizations. All of the state universities in the United States are secular organizations (especially because of the First Amendment of the United States Constitution) while some private universities are connected with the Christian or Jewish religions. Among many of these, seven prominent examples are: Baylor University, Brigham Young University, Boston College, Emory University, the University of Notre Dame, Duquesne University, Southern Methodist University, and Yeshiva College.

The public university systems of the United Kingdom, Australia, New Zealand, Canada, and Japan are also secular, although some government-funded primary and secondary schools may be religiously aligned in some countries.
