Ushakovo, Novomoskovsky Rural Okrug, Guryevsky District, Kaliningrad Oblast

Ushakovo (; or ""; ; ) is a village in the Russian enclave Kaliningrad Oblast. It is situated at the mouth of the Prokhladnaya River () at the Vistula Lagoon.
The Battle of Pokarwis between pagan Prussians and the Teutonic Knights took place nearby in 1261. The Teutonic Knights founded the village as "Brandenburg" to honor Otto III, Margrave of Brandenburg who supported the order in the Prussian Crusade, and erected a castle in 1266. It became known as "Brandenburg (Frisches Haff)" and "Brandenburg in Ostpreußen" to differentiate it from Brandenburg an der Havel.
