Bachelor of Laws (Latin: Legum Baccalaureus; LL.B. or B.L.) is an undergraduate degree in law (or a first professional degree in law, depending on jurisdiction) originating in England and offered in Japan and most common law jurisdictions—except the United States and Canada—as the degree which allows a person to become a lawyer. It historically served this purpose in the U.S. as well, but was phased out in the mid-1960s in favor of the Juris Doctor degree, and Canada followed suit.
Historically, in Canada, Bachelor of Laws was the name of the first degree in common law, but is also the name of the first degree in Quebec civil law awarded by a number of Quebec universities. Canadian common-law LL.B. programmes were, in practice, second-entry professional degrees, meaning that the vast majority of those admitted to an LL.B. programme were already holders of one or more degrees, or, at a minimum (with very few exceptions), have completed two years of study in a first-entry, undergraduate degree in another discipline. Currently, Bachelor of Laws is also the name of the first degree in Scots law and South African law (both being pluralistic legal systems that are based partly on common law and partly on civil law) awarded by a number of universities in Scotland and South Africa, respectively.
