Yaghnobi is an Eastern Iranian language spoken in the upper valley of the Yaghnob River in the Zarafshan area of Tajikistan by the Yaghnobi people. It is considered to be a direct descendant of Sogdian and has sometimes been called Neo-Sogdian in academic literature. There are some 12,500 Yaghnobi speakers, divided into several communities. The principal group lives in the Zafarobod area. There are also resettlers in the Yaghnob Valley. Some communities live in the villages of Zumand and Kůkteppa and in Dushanbe or its vicinity.

The Yaghnobi people are an East Iranian ethnic minority in Tajikistan. They inhabit Tajikistan's Sughd province in the valleys of the Yaghnob, Qul and Varzob rivers. The Yaghnobis are considered to be descendants of the Sogdian-speaking peoples who once inhabited most of Central Asia beyond the Amu Darya River in what was ancient Sogdia.
