Bachelor of Laws (Latin: Legum Baccalaureus; LL.B.) is an undergraduate law degree in the United Kingdom and most common law jurisdictions. Bachelor of Laws is also the name of the law degree awarded by universities in Australia, People's Republic of China, Hong Kong S.A.R., Macau S.A.R., Malaysia, Bangladesh, India, Japan, Pakistan, Uganda, Kenya, Ghana, New Zealand, Nigeria, Singapore, South Africa, Botswana, Israel, Brazil, Tanzania, Zambia, and many other jurisdictions.

In the United States, the Bachelor of Laws was the primary law degree until the 1960s, when it was phased out in favour of the Juris Doctor. Canadian practice followed suit in the early 21st century, phasing out the Bachelor of Laws for the Juris Doctor.
