Bachelor of Medicine, Bachelor of Surgery (MBBS)

A Bachelor of Medicine, Bachelor of Surgery (Latin: Medicinae Baccalaureus, Baccalaureus Chirurgiae; MBBS: is an undergraduate medical degree awarded by medical schools in countries that follow the tradition of the United Kingdom. The historical degree nomenclature states that they are two separate undergraduate degrees. In practice, however, they are usually combined as one and conferred together, and may also be awarded at graduate-level medical schools. It usually takes five to six years to complete this degree.

A Bachelor of Medicine (MB) is an undergraduate medical degree awarded by medical schools in countries that follow the tradition of China. It usually takes five to six years to complete. The word "Medicine" in this degree stands for the general term of medical science and practice rather than internal medicine. Hence, these medical graduates with an MB degree can also practice surgery. The MB degree is considered as the primary medical degree and its holder may pursue a Master of Medical Science and a Doctor of Medical Science (PhD-equivalent) for furthering their professional education.

Both degrees are considered equivalent to the Doctor of Medicine degree conferred by United States universities and medical institutions.  In North America, the equivalent medical degree is awarded as Doctor of Medicine or Doctor of Osteopathic Medicine—the latter in the United States only.
