# Outline of academic disciplines

An academic discipline or field of study is a branch of knowledge, taught and researched as part of higher education. A scholar's discipline is commonly defined by the university faculties and learned societies to which they belong and the academic journals in which they publish research.
Disciplines vary between well-established ones in almost all universities with well-defined rosters of journals and conferences and nascent ones supported by only a few universities and publications. A discipline may have branches, which are often called sub-disciplines.
The following outline provides an overview of and topical guide to academic disciplines. In each case, an entry at the highest level of the hierarchy (e.g., Humanities) is a group of broadly similar disciplines; an entry at the next highest level (e.g., Music) is a discipline having some degree of autonomy and being the fundamental identity felt by its scholars. Lower levels of the hierarchy are sub-disciplines that do generally not have any role in the structure of the university's governance.
