The Democratic Party of Iranian Kurdistan (PDKI; Kurdish: حیزبی دێموکراتی کوردستانی ئێران, romanized: Hizbi Dêmukrati Kurdıstani Êran, HDKA; Persian: حزب دموکرات کردستان ایران, romanized: Ḥezb-e Demokrāt-e Kordestān-e Īrān), also known as the Kurdish Democratic Party of Iran (KDPI), is an armed leftist separatist movement of Kurds in Iran, exiled in the Kurdistan Region of Iraq with branch offices in Europe.

It is the oldest of all Kurdish parties, which are fighting for Kurdish rights in Iran. It is banned and declared a terrorist organization in Iran and thus not able to operate openly. Over the years the group has shifted its focus from an independent Kurdish state to autonomy or the implementation of a federal system in Iran.

Since 1979, KDPI has waged a persistent guerrilla war against Iran. This included the 1979–1989 Kurdish insurgency, its 1989–1996 insurgency and the recent clashes in 2016. Another noteable action is the 1967 Kurdish revolt in Iran.
