Mohammad Reza Heydari (Persian: محمد رضا حیدری; born 12 October 1966) is a former Iranian consul in Oslo who resigned his post in January 2010 in acting against his own country's Government.

Mohammed Reza Heydari told the Norwegian broadcaster NRK that his decision to step down was tied to the crackdown, during which security forces fired directly into crowds.

"If they (Iranian officials) move in the direction of violence, they will not be able to control the system and we might move in the direction in which Iran's unity then might be compromised all together," Mohammed Reza Heydari, Iran's former down graded staff in consular section of Iranian Embassy in Oslo, Norway, told CNN's Christiane Amanpour.

He said that he hopes the strikes, civil disobedience, and non-violent protests in his homeland will "break the back" of the government and force it to listen to what the people say.

Mohammad Reza Heydari persuaded the other Iranian diplomats and the members of staff at the Ministry of Foreign Affairs in Tehran to join this campaign and instead of being representatives of a 'coup d'état government' as he calls it, become, in his opinion, the ambassadors of their right-seeking nation.
