The Islamic Republic of Iran and Hashemite Kingdom of Jordan share a long but complicated relationship which has, at times, been tense and unstable.

[4] The outbreak of Iranian Revolution and subsequent establishment of an Islamic republic in Iran changed their relationship drastically from positive to negative.

[9][10][11] Jordan was also alleged to have been working with Saudi Arabia, Russia, and Israel in an attempt to curb Iranian involvement in Syria.

[12] On July 19, 2021, US president Joe Biden met with Jordanian King Abdullah II and discussed, among other things, the future of the Syrian crisis.

Jordan also shares similar political structure with Saudi Arabia, both are Arab monarchies and closely tied to the West.

Growing Iranian influence brought Jordan and Saudi Arabia closer, with both denouncing Iran together in spite of the rise of Crown Prince Mohammed Bin Salman.

[16] Some have alleged Saudi Arabian and Israeli involvement in the failed April 2021 coup attempt in Jordan, which has been related to Jordanian unofficial opposition to the 'deal of the century' proposed by the United States as a solution to the Israeli-Palestinian Conflict.

[18] On the other side, Jordan feared the escalation of tensions between Qatar and its Gulf neighbors Saudi Arabia, Bahrain and the United Arab Emirates might give Iran an upper hand.

[23] Some Jordanian politicians such as Zaid Nabulsi, a member of the king's advisory board, and Mouafaq Mahadeen, a journalist with close ties to the ruling family, have also began promoting the idea of Iranian religious tourism to the shrine of Jafar ibn Abu Talib in the city of Karak, the home of Jordan's Shiite minority.

In 2004, Jordanian King Abdullah II accused Ahmed Chalabi, an Iraqi, of being an Iranian agent conspiring to attack Jordan.
