The Islamic Republic of Iran has, since 1979 and the Iran hostage crisis, engaged in repeated detentions of foreign or dual nationals. These detentions have lasted for extended periods, with a documented history of using the detained party as a bargaining chip in diplomatic negotiations. The list below of current and former detainees in Iran excludes people abducted in other countries and brought into the country.

Hostage diplomacy

Since the Iran hostage crisis, the Islamic Republic of Iran has engaged in a pattern of detaining foreign nationals for extended periods. According to the Center for Human Rights in Iran, the Iranian government has imprisoned dual and foreign-only nationals "as bargaining chips in its dealings with other nations." Iran's repeated dubious detention of dual citizens and thereafter bargaining behavior have led observers to qualify the practice as a policy of hostage diplomacy.

According to French ex-hostage Louis Arnaud, who spent two years in Iranian custody, those detained are usually kept in solitary confinement. In an interview, he said that "Everything is done so that you are deprived of your humanity".

Detainees Dual nationals of Iran and another country are particularly vulnerable to arbitrary detention because under the international Master Nationality Rule and treaty, "a State may not afford diplomatic protection to one of its nationals against a state whose nationality such person also possesses".

According to Human Rights Watch, "Iranian authorities have violated detainees' due process rights and carried out a pattern of politically motivated arrests." In November 2017, Reuters reported that Iran's Islamic Revolutionary Guard Corps (IRGC) had arrested "at least 30 dual nationals during the past two years, mostly on spying charges."

Reactions In September 2019, on the sidelines of the Seventy-fourth session of the United Nations General Assembly, families of dual and foreign nationals imprisoned in Iran as well former dual and foreign nationals imprisoned in Iran launched the Alliance Against State Hostage Taking."

In January 2023, France called for the release of seven nationals, who were held in Iran. One of the detainees, Fariba Adelkhak was arrested in June 2019, along with her colleague Roland Marchal. While Marchal was released in 2020, Fraiban Adelkhak remained in prison until 2023.
