The coat of arms of the Tajik Autonomous Soviet Socialist Republic circa 1929. "Tajik Autonomous Soviet Socialist Republic" is written (from top to bottom) in Tajik Latin, Tajik Arabic, and Russian Cyrillic.

The Tajik language has been written in three alphabets over the course of its history: an adaptation of the Arabic script (specifically the Persian alphabet), an adaptation of the Latin script, and an adaptation of the Cyrillic script. Any script used specifically for Tajik may be referred to as the Tajik alphabet, which is written in Tajik as follows: Persian alphabet: Persian: ‫اﻟﻔﺒﺎی تاجیکی‬, Cyrillic: алифбои тоҷикӣ, Latin: alifboi toçikī. The use of a specific alphabet generally corresponds with stages in history, with Arabic being used first, followed by Latin for a short period and then Cyrillic, which remains the most widely used alphabet in Tajikistan. A related language, Judæo-Tajiki, spoken by the Bukharan Jews, traditionally used the Hebrew alphabet but more often today is written using the Cyrillic variant.
