Bachelor of Arts (B.A. or A.B.), from the Latin artium baccalaureus, is a bachelor's degree awarded for an undergraduate course or programme in either the liberal arts, the sciences or both.

A Bachelor of Arts degree programme generally lasts three years in nearly all of the European Union countries as well as in Australia, Bosnia and Herzegovina, Croatia, India, Iraq, Israel, New Zealand, Iceland, Norway, the Canadian province of Quebec, Singapore, the Caribbean, South Africa and Switzerland, whereas it usually lasts four years in Azerbaijan, Bangladesh, Canada (outside Quebec), Brazil and Latin America, Japan, Pakistan, Scotland, the Russian Federation, Tunisia, Turkey, Egypt and the United States.

Diplomas generally give the name of the institution, signatures of officials of the institution (generally the president or rector of the university as well as the secretary or dean of the component college), the type of degree conferred, the conferring authority and the location at which the degree is conferred. Degree diplomas generally are printed on high quality paper or parchment, use ornate lettering and often include archaic terminology or languages. Individual institutions set the preferred abbreviation for their degrees.
