An academic discipline or field of study is a branch of knowledge that is taught and researched as part of higher education. A scholar's discipline is commonly defined by the university faculties and learned societies to which he or she belongs and the academic journals in which he or she publishes research.
Disciplines vary between well-established ones that exist in almost all universities and have well-defined rosters of journals and conferences and nascent ones supported by only a few universities and publications. A discipline may have branches, and these are often called sub-disciplines.
The following outline is provided as an overview of and topical guide to academic disciplines.
