Two Centuries of Silence (Persian: دو قرن سکوت, romanized: Do Qarn Sokut, pronounced [d̪o ɢæɾn soˈkʰuːt̪ʰ]) is a book written in Persian by Abdolhossein Zarrinkoub, a prominent Iranian scholar of Iran's culture, history and literature.

Zarrinkoub presents a lengthy discussion on the large flux and influence of the Arabs on the literature, language, culture and society of Persia during the two centuries following the Islamic conquest of Iran.

Zarrinkoub discusses how the Arab/Islamic conquest was followed by almost "two centuries of silence" socially, culturally, and politically of native Persians.

Many such instances were occasions that in the past―either due to immaturity or by prejudice―I had been unable to rightly acknowledge the faults, iniquities, and defeats of Iran."

[2] In his extensive introductory essay, Sprachman offers an analysis as how Zarrinkub was compelled to change his historical view of Iranian history after the 1979 Revolution[3] The book was earlier translated by Avid Kamgar (Aug. 19, 2016) and published by Oughten House Publications.
