The Vyatichs (Вятичи in Russian) were a tribe of Early East Slavs, which inhabited a part of the Oka basin.

The Primary Chronicle names a certain tribal leader Vyatko as the forefather of the tribe. The Vyatichs were mainly engaged in farming and cattle-breeding . Between the 9th and 10th centuries, the Vyatichs were paying tribute to the Khazars and later Kievan princes. The tribe, however, was constantly trying to defend its own political independence up until the early 12th century. By the 11th century, the Vyatichs had already populated the Moskva basin and the area of today's Moscow. In the 11th and 12th centuries, the tribe founded a number cities due to developing handicrafts and increasing trade, including Moscow (or what would be Moscow proper), Koltesk , Dedoslav , Nerinsk and others. In the second half of the 12th century the land of the Vyatichs was distributed among the princes of Suzdal and Chernigov. The last direct reference to the Vyatichs was made in a chronicle under the year of 1197. Indirect references, however, may be traced to the early 14th century.

There are numerous archeological monuments in Moscow that tell historians about the Vyatichs. Their fortified settlements of the 11th century were located in the historical center of today's Moscow, namely, the Borovitsky Hill , Kolomenskoye (the spot of the former Diakovskoye village), Kuntsevo (a district of Moscow) and others. One may also find traces of the Vyatich settlements in Brateyevo, Zyuzino, Alyoshkino, Matveyevskoye and other localities of Moscow. Burial mounds with cremated bodies have been found along the upper reaches of the Oka and Don.
