Sayyid Hassan Aghaee Firouzabadi (Persian: حسن فيروزآبادی; 3 February 1951 – 3 September 2021) was an Iranian military officer. He served as the Chief-of-Staff of the Iranian Armed Forces—the most senior military authority in Iran—from 1989 to 2016.^[4] After that, he was appointed a senior military advisor to the Supreme Leader of Iran^[5] and a member of the Expediency Discernment Council.^[6]

Firouzabadi was born on 3 February 1951^[1] in the town of Malabad, in Mashhad, Iran, to religious parents who came from Yazd.^[7] He studied at the Ferdowsi University of Mashhad, graduating in 1980, one year after the Iranian Revolution.^[8] He then took a part in the Iran–Iraq War and rose in prominence. He was in charge of the industrial war engineering, and the committee for the construction of surface-to-surface missiles. After the end of the war on 25 October 1989, Ali Khamenei appointed him head of the General Staff.^[8]

Before he was appointed the chief-of-staff, Firouzabadi had no previous military experience from either the Islamic Revolutionary Guard Corps (IRGC), or the Islamic Republic of Iran Army (Artesh), and he went by the title Basiji.^[9] On 17 April 1995, Supreme Leader Ali Khamenei granted him the rank of major general, practically the highest military rank available in Iran.^[10] According to a report published by The Washington Institute for Near East Policy, he was credited with "leading the IRGC from a war-ravaged organization to a hybrid conventional-asymmetric military force overshadowing the still-lagging Artesh.^[11] He also oversaw a growing military industry that produced a wide range of products amid international sanctions, from ammunition to space rockets".^[4]

Firouzabadi expressed anti-American sentiment, rejecting a letter sent to him by the US Congress and said that "the scourge of Americans were a threat to the Revolution."^[15][16]

Firouzabadi was a supporter of former president Mahmoud Ahmadinejad's ideology and called on the Higher National Defense University to add to his ideology.^[17] Defending the continuation of Ahmadinejad's presidency, he also said in a speech that provoked criticism from most of the presidential candidates: "Now some believe that the distance that groups of politicians have created between the government and the people has been successful and has been able to attract the attention of the people. Therefore, in this presidential election, they can nominate a new presidential candidate and end the issue of Ahmadinejad. But this does not happen, they make mistakes". He further criticized former president Mohammad Khatami.^[18] However, towards the end of Ahmadinejad's presidency, he became critical of Ahmadinejad's positions.^[19][20]

According to media reports on 3 September 2021, Firouzabadi died at the age of 70 from COVID-19, amid the COVID-19 pandemic in Iran.^{[21][22][23][24]} A funeral attended by senior military commanders was held in Tehran on Saturday 4 September.^[25][26]
