Traidenis (Polish: Trojden; Belarusian: Трайдзень; died 1282) was Grand Duke of Lithuania from around late 1267 to 1268 until 1282. He is the second most prominent grand duke of Lithuania in the 13th century after Mindaugas. His reign ended a seven-year unrest period after Mindaugas was assassinated in 1263 and firmly established the Grand Duchy as a pagan state for another hundred years.
Traidenis expanded the Grand Duchy into the territories of Sudovians and Semigalians and strengthened its presence in Black Ruthenia. Unlike Mindaugas, Traidenis did not concentrate on expansion into the east.
