Znojemský; d. 1161), a member of the Přemyslid dynasty[citation needed], was a Bohemian prince who ruled in the Moravian principality of Znojmo from 1123 to 1128 and again from 1134 until his death.

From 1115 onwards, both the Brno and Znojmo principalities in Moravia were held by Soběslav I, youngest son of the late King Vratislaus II of Bohemia.

Finally, when Soběslav fell out with his elder brother Duke Vladislaus I of Bohemia in 1123, Conrad II was able to succeed his father in Znojmo.

However, Duke Vladislaus died two years later and as the dynastic struggles culminated in the 1126 Battle of Chlumec, Soběslav had Conrad II deposed and imprisoned at Dohna Castle in 1128.

However, while the castle was successfully defended by the duke's younger brother Prince Děpold I of Jamnitz, Vladislaus II himself proceeded to the court of King Conrad III of Germany in Würzburg and returned with a large royal army.
