Iranian Armenians (Armenian: իրանահայեր, romanized: iranahayer; Persian: ایرانی های ارمنی), also known as Persian Armenians (Armenian: պարսկահայեր, romanized: parskahayer; Persian: ارامنه فارس), are Iranians of Armenian ethnicity who may speak Armenian as their first language. Estimates of their number in Iran range from 70,000 to 500,000. Areas with a high concentration of them include Tabriz, Tehran, Salmas and New Julfa, Isfahan.
Armenians have lived for millennia in the territory that forms modern-day Iran. Many of the oldest Armenian churches, monasteries, and chapels are in Iran. Iranian Armenia (1502–1828), which includes what is now the Armenian Republic, was part of Qajar Iran up to 1828. Iran had one of the largest populations of Armenians in the world, alongside the neighbouring Ottoman Empire until the beginning of the 20th century.
Armenians were influential and active in modernizing Iran during the 19th and 20th centuries. After the Iranian Revolution, many Armenians emigrated to Armenian diasporic communities in North America and Western Europe. Today, the Armenians are Iran's largest Christian religious minority.
