Standard Persian (Persian: فارسی معیار) is the standard variety of Persian that is the official language of Iran and Tajikistan and one of the two official languages of Afghanistan. It is a set of spoken and written formal varieties used by the educated persophones of several nations around the world.

As Persian is a pluricentric language, Standard Persian encompasses various linguistic norms (consisting of prescribed usage). Standard Persian practically has three standard varieties with official status in Iran, Afghanistan, and Tajikistan. The standard forms of the three are based on the Tehrani, Kabuli, and Bukharan varieties, respectively.
