Regional accreditation is a term used in the United States to refer to the process by which one of several accrediting bodies—each primarily serving one of six defined geographic areas of the country—accredits schools, colleges, and universities. Accreditation is a voluntary system of self-regulation, supported by peer-review, in which an institution or program is assessed against a set of standards. Each regional organization oversees the accreditation review process and maintains accreditation statuses for the majority of public and non-profit private educational institutions in the region it serves.

Regionally accredited schools are predominantly academically oriented, non-profit institutions. Nationally accredited schools, by contrast, are predominantly for-profit and offer vocational, career or technical programs. Each college has the right to set standards and determine how transfer credits are accepted, though it may be difficult to transfer credits (or even credit for a completed degree) from a nationally accredited school to one that is accredited regionally (and vice-versa). Some regionally accredited colleges refuse to accept any credits from nationally accredited schools, while others are reluctant to accept them because they have concerns about academic standards or are generally unfamiliar with a particular school. Any student who is planning to transfer credits from a nationally accredited school to a regionally accredited school should ensure that the regionally accredited school will accept the credits before they enroll in the nationally accredited school.
