The Ukrani are a West Slavic Polabian tribe in the Uckermark (terra U(c)kera, Uckerland) from the 6th–12th centuries.

Their settlement area is centered around the lakes Oberuckersee and Unteruckersee at the spring of the Uecker River.

In this region, burghs with a proto-town suburbium are set up at Drense and on an isle in Lake Oberuckersee (near modern Prenzlau).
