Across the water
Iran and Saudi Arabia face each other across the Persian Gulf, a name Arab states often replace with "Arabian Gulf". They have no land border. Each sees itself as a leader of the Muslim world, and they have long competed for influence in Iraq, Syria, Lebanon, Yemen and Bahrain.
Iran is a Persian-speaking, mainly Shia country. Since the 1979 revolution it has been an Islamic Republic with elected institutions under a clerical Supreme Leader. Saudi Arabia is an Arabic-speaking, mainly Sunni absolute monarchy, ruled by the Al Saud family since the kingdom was founded in 1932. It is also custodian of Mecca and Medina.
Breaking and mending ties
The rivalry sharpened after 1979, and relations have broken down more than once. In January 2016 Saudi Arabia cut diplomatic ties after its embassy in Tehran was stormed by protesters. The protests followed the kingdom's execution of the Shia cleric Nimr al-Nimr. Through the Yemen war that began in 2015, Saudi Arabia led a coalition against the Houthi movement, which is backed by Iran.
In March 2023 the two governments agreed in Beijing to restore relations, in a deal brokered by China, and embassies reopened later that year. That détente was tested in 2026. During the war that began on 28 February with US and Israeli strikes on Iran, Iranian missiles and drones struck targets across the Gulf, including in Saudi Arabia. As of late 2026, the conflict and the region's security outlook remained unsettled.
Oil giants with different economies
Both were founding members of OPEC in 1960, and both hold some of the world's largest oil reserves. Iran also shares the world's largest natural gas field with Qatar (South Pars / North Field). Saudi Arabia has used oil wealth and its Vision 2030 programme to court foreign investment and tourism. Iran's economy has been constrained for decades by sanctions over its nuclear programme, and its currency has lost much of its value.
Different societies
Iran's population is more than double Saudi Arabia's. It has an ancient urban culture: Persian poetry, carpet weaving and a calendar that starts the year at Nowruz in March. Saudi Arabia's identity centres on Arabian tribal heritage and its role in Islam, and its population is younger and growing faster. For other angles, compare Iran vs Iraq or Turkey vs Saudi Arabia.
