In the academic study of Christian and Unitarian Universalist theology, the Master of Divinity (M.Div., magister divinitatis in Latin) is the first professional degree of the pastoral profession in North America. It is the most common academic degree in seminaries and divinity schools.

In many Christian denominations, and of some other religions, this degree is the standard prerequisite for ordination to the priesthood or pastorship or other appointment, ordination or licensing to professional ministry. At accredited seminaries in the United States this degree requires between 72 and 90 credit hours of study (72 being the minimum determined by academic accrediting agencies and 90 being on the upper end of certain schools that wish to ensure a broader study of the related disciplines).

It generally includes studies in Christian ministry and theology. Coursework usually includes studies in New Testament Greek, theology, philosophy, church history, pastoral theology, Hebrew Bible (Old Testament), and New Testament studies. Many programs also contain courses in church growth, ecclesiology, evangelism, systematic theology, Christian education, liturgical studies, Latin, Hebrew, canon law, patristics, and the like. The degree may or may not include a thesis.

The Master of Divinity has replaced the Bachelor of Divinity in most United States seminaries as the first professional degree, since the latter title implied in the American academic system that it was on a par with a Bachelor of Arts or other basic undergraduate education even though a bachelor's degree was and remains a prerequisite for entrance into graduate divinity programs.

The M.Div. is a significantly more extensive program than most master's degrees. In the United States the degree usually consists of well over 90 semester hours, as opposed to the usual 36 or 48. Ordination in most mainline Protestant denominations and the Roman Catholic Church thus requires seven or eight years of education past high school: the first four in undergraduate studies leading to a bachelor's degree (which may or may not be in a related field) and then three or four years of seminary or divinity school education leading to the M.Div.

The M.Div. stands in contrast to the M.A. in Theology and Master of Theological Studies (M.T.S.), the usual academic degrees in the subject (which tend not to include "pastoral" or "practical" courses), and the Bachelor of Sacred Theology (S.T.B.), Licentiate in Sacred Theology (S.T.L.), Master of Theology (M.Th.), Master of Sacred Theology (S.T.M.), and Master of Religion (M.Rel.), which are also academic degrees. Schools with Pontifical faculties in North America often award both the M.Div. and S.T.B. at the same time after a three year period of graduate studies.

In the United States and Canada the M.Div. is a first professional degree. Occasionally a Master of Divinity graduate pursues doctoral studies, often the Doctor of Ministry (D.Min.), which is also a degree focused on ministerial practice. The Master of Theology (Th.M.), Master of Sacred Theology (S.T.M.), Doctor of Theology (Th.D.), Doctor of Philosophy (Ph.D.), and Doctor of Sacred Theology (S.T.D.) all tend to be academic rather than ministerial degrees. In recent years it is not unusual for holders of the M.Div. to add another degree, earning either the Ph.D. or Th.D. as well as the D.Min. Graduates of the M.Div. who completed a thesis as part of their degree are often eligible for admission into Ph.D. or Th.D. programs with a requirement to take additional, more academic-oriented, coursework. While the Doctor of Divinity is only an honorary degree in the United States, in the United Kingdom the Doctor of Divinity (D.D.) is the highest degree in the field at most universities, normally awarded for a significant body of published work of high quality.
