MBBS, Medicinae Baccalaureus Baccalaureus Chirurgiae in Latin, or Bachelor of Medicine and Bachelor of Surgery (abbreviated in many ways, e.g. MBBS, MB ChB, MB BCh, MB BChir (Cantab), BM BCh (Oxon), BMBS), are the two first-professional degrees in the medicine and surgery field awarded upon graduation from the medical school of universities in countries that adopt the tradition of the United Kingdom.

They should have belonged to two separate undergraduate degrees. But practically they are usually considered as one degree and conferred together.
