A non-denominational church (usually Christian) is a religious organization which does not necessarily align its mission and teachings to an accepted denomination. It is also often done to allow the church to govern themselves without interference from the policies of a national organization, in regards to budgets, memberships, policies, formal standards, and public image.

Non-denominational churches are often more accepting of people from various religious backgrounds and more tolerant of differing viewpoints. Critics feel however, that there cannot be a true non-denominational church as they all adhere to a core set of beliefs, though that set of beleifs may not be formalized as specific denomination. While many non-denominational churches may be indistinguishable from an established denomination in teachings, they are usually free to change those teachings to better suit the church members, free of strict policies set down by a parent organization.
