Tofa is a Turkic language spoken in the Irkutsk region of the Russian Republic by 93 people. It is closely related to Tuvan. Tofa speakers live in the villages of Tofalarskaya (Тофаларского) and Nerkha (Нерхинского), which are part of the Nizhneudinskiy district (Нижнеудинского района) of Irkutsk.
Until 1988 Tofa was unwritten, except in the works of scholars, who used the Cyrillic and Latin alphabets to write the language. A version of the Cyrillic alphabet for Tofa was adopted in 1988.
