The Democratic Party of Iranian Kurdistan, also known as the Kurdish Democratic Party of Iran (KDPI), is an armed leftist ethnic party of Kurds in Iran, exiled in northern Iraq. It is banned in Iran and thus not able to operate openly. The group calls for self-determination of Kurdish people, and has been described as seeking either separatism or autonomy within a federal system.

Kurds in Iran constitute a large minority in the country with a population of around 9 and 10 million people.
