The Bachelor of Theology degree (BTh, ThB, or BTheol) is a two- to five-year undergraduate degree or graduate degree in theological disciplines and is typically (but not exclusively) pursued by those seeking ordination for ministry in a church, denomination, or parachurch organization. Candidates for this degree typically must complete course work in Greek and (or) Hebrew, as well as systematic theology, biblical theology, ethics, homiletics, hermeneutics, counseling and Christian ministry. The Bachelor of Theology may include a thesis component and may consist of an additional year beyond the coursework requirements for the degrees of Bachelor of Religious Education and Bachelor of Arts. In some denominations, such as the Church of England or the Presbyterian Church in America, it is considered sufficient qualification for formal ordination.

In the United Kingdom and other European nations, the Bachelor of Theology is a two to five year degree for students pursuing ordination.
