Hassan Abbasi (Persian: حسن عباسی) is an Iranian conspiracy theorist and an Islamic Revolutionary Guard Corps officer who heads its think-tank 'Center for Borderless Security Doctrinal Analysis'.

[8] Jahangir Arasli, an Azerbaijani intelligence analyst, wrote in 2007 that Abbasi was among those in charge of devising the concept of asymmetric response at Imam Hussein University.

[10] After Clifford May,[11] Amir Taheri has dubbed him "the Kissinger of Islam" in a The Telegraph article,[12] and also quoted an anonymous European diplomat in Tehran saying "to Iran's new ruling elite, Abbasi is the big strategic brain".

[15] Raz Zimmt classifies him among the prominent figures of the radical right wing of Iranian politics, along with Mehdi Ta'eb, Alireza Panahian, Said Qasemi and Qasem Ravanbakhsh who all serve in the central committee of 'Ammar Headquarters', an IRGC-affiliated institution established in 2011.

[18] In February 2019, he gave a speech condemning President Hassan Rouhani, Speaker Ali Larijani, and Foreign Minister Mohammad Javad Zarif for having supported the Joint Comprehensive Plan of Action telling them to "go to hell" and that the Iranian people would "spit" on them, seen as expressing the IRGC's growing resentment over the nuclear deal and its fallout.
