One of the most significant political and identity disputes surrounding Iran’s football team at the 2026 World Cup centers on the flag that will be seen in stadiums across the United States, Canada, and Mexico.

Recently, The Athletic, citing sources, reported that FIFA’s official stadium guidelines for the 2026 World Cup might ban the entry of Iran’s Lion and Sun flag, a symbol that in recent years has become a primary emblem for many opponents of the Islamic Republic at sports matches, political rallies, and international events.

Although FIFA has not yet responded to the report, its publication triggered widespread reactions among sections of the Iranian diaspora and political groups opposed to the Islamic Republic.

The Football Federation of the Islamic Republic of Iran had previously announced that “one of its conditions” for participating in the World Cup was a ban on the entry of any flag other than the official flag of the current government.

Will FIFA be willing to accept such a request? What do we know about the campaigns launched by Iranians abroad to bring the Lion and Sun flag into stadiums, and the protests by political and civil organizations against FIFA’s potential decision?
