Tehran University of Medical Sciences (TUMS) (Persian: دانشگاه علوم پزشکی تهران‎, Danushgah-e 'lum Pezeshki-ye Tehran) is the largest and most highly-ranked medical university of Iran. In September 2008, Iran's Minister of Health, Treatment, and Medical Education, Dr. Lankarani, called TUMS a pioneer in research throughout the country with a noticeable lead over its peer universities. 

The first modern center of medical training in Iran was founded in 1851. It was a part of the Institute of Higher Education (Dar-ol-Fonoon). The School of Medicine was established as a part of University of Tehran in 1934. After the Islamic Revolution, medical schools and departments associated with medical fields were separated from the Ministry of Higher Education and were taken under the administration of the Ministry of Health, Treatment, and Medical Education. 

Since 1986, all those schools of University of Tehran which specialize in medical fields have carried on their activities independently as Tehran University of Medical Sciences and Health Services. TUMS is the oldest and most well-known medical center in Iran, nationally as well as internationally. 

TUMS, as one of the country’s top research universities, accepts applications from the most qualified students. It also has the largest schools of medicine, dentistry, pharmacy, rehabilitation, allied medical sciences, public health, advanced technologies in medicine, nutritional sciences and dietetics, and nursing and midwifery in Iran as well as a virtual school.
