The Uliches or Ugliches (Уличи (Угличи) in Russian, Уличі (Угличі) in Ukrainian) were a tribe of Early East Slavs who, between the eighth and the tenth centuries, inhabited (along with the Tiverians) Bessarabia, and the territories along the Lower Dnieper, Bug River and the Black Sea littoral.
The tribal name comes from a location called Oglos or Onglos by the Byzantine chroniclers Theophanes the Confessor and Nikephoros I of Constantinople, possibly to be identified with Peuce Island. The word may derive from Slavic âgul, "corner", or, according to Stephen Runciman, from agul, "enclosure".
The Uliches long struggled against the Kievan princes Oleg, Igor and Sviatoslav Igorevich for their independence, until a Kievan commander Sveneld captured their capital, Peresechen (near Orhei, in present-day Moldova), around 940. In the mid-10th century the Ulich lands paid tribute to Sveneld. The Uliches were last mentioned in the 970s.
