Mostafa Moeen, M.D. (مصطفی معین; born 1 April 1951 in Najafabad), is an Iranian politician and professor of Pediatrics, and an advisor to the former President Mohammad Khatami. He was a presidential candidate for the 2005 Iranian presidential election. His campaign enjoyed the support of some reformist parties and organizations, headed by the Islamic Iran Participation Front (IIPF).
Currently, he is the director of Immunology, Asthma and Allergy Research Institute, affiliated to Tehran University of Medical Sciences (TUMS).
Early life 
Moeen was born in 1951 in the city of Najaf Abad. At age 18, he was accepted to Shiraz University medical school , and after the Iranian Revolution, he was appointed as the president of Shiraz University. He was elected as representative of Shiraz in mid-term elections of the first Parliament of Iran in 1982.
Ministration term 
Moeen was the Minister of Culture and Higher Education under President Akbar Hashemi Rafsanjani (1989-1993) and President Mohammad Khatami (1997-2000), and later became the Minister of Science, Research, and Technology (the same post, with a changed name) under President Khatami (2000-2003). As a Minister, Moeen resigned after the student protests of July 1999, and again in July, 2003 after he failed to persuade the Council of Guardians to redirect his ministry towards his vision of higher "scientific productivity".
Presidential ambition 
On October 12, 2004, Mir-Hossein Mousavi declined to run for the presidency, causing the Islamic Iran Participation Front to consider Moeen instead. IIPF members soon announced his nomination. On December 29, 2004, Moeen agreed to run for the presidency, as the first major candidate to announce his participation.
Contrary to the general expectations and the poll results, Moeen, who was expected to be among the first three most popular candidates in the first round, fared poorly and ranked fifth in the end, with the election resulting in a run-off between Akbar Hashemi Rafsanjani and Mahmoud Ahmadinejad.
Moeen's present campaign was headed by Ali Shakouri-Rad, and he was supported by the following political parties and organizations:
- Islamic Iran Participation Front
- Mojahedin of the Islamic Revolution Organization (sāzmān-e mojāhedin-e enghelāb-e eslāmi)
- Movement for Liberation of Iran (nehzat-e āzādi-e irān)
- Council of National-Religional Forces (shorāy-e niruhāy-e melli mazhabi)
- Islamic Association of the Medical Society (anjoman-e eslāmi-e jāme'e-ye pezeshki)
- Islamic Association of the Teachers (anjoman-e eslāmi-e mo'allemān)
- Islamic Association of University Lecturers (anjoman-e eslāmi-e modarresin-e dāneshgāh-hā)
