The Ungern-Sternberg family or von Ungern-Sternberg is an old and influential Baltic-German nobility, with branches belonging to the German, Finnish, Swedish and Russian nobility.

The house traces its origins to Hans Ungern (Ungern in German translates to "Hungarian"), who in 1269 became a vassal of the Archdiocese of Riga. On 29 March 1277, we learn that Rudolf von Ungern-Sternberg took part in the defence of Tallinn within the ranks of the Lithuanian army against a Russian invasion. By virtue of this ancient valour, in 1653 the family was granted the baronial title by Queen Christina of Sweden.

In 1874, one branch of the family received the comital title within the Russian Empire, altering their surname to Ungern-Šternbergov. The motto of the house is Звезда их не знает заката ("their star knows no sunset").
