|Wyszes?awa of Kiev|
|Duchess consort of Poland|
|Spouse||Boles?aw II the Bold|
|Father||Sviatoslav II of Kiev|
Wyszeslawa Sviatoslavna of Kiev (Russian: , romanized: Vysheslava Svyatoslavna, Polish: Wyszes?awa ?wiatos?awówna) (b. ca. 1047? - d. aft. 1089), was a Kievan Rus' princess and member of the Rurikid dynasty and by marriage Duchess and later Queen of Poland.
The chronicler Jan D?ugosz and other authors reported her parentage. She was certainly married to Boles?aw II the Bold, Duke of Poland before 1069, because in that year their only child, Mieszko, was born. She was probably crowned Queen of Poland with her husband on Christmas Day of 1076 in the Gniezno Cathedral by the Archbishop Bogumi?.
In 1079, together with her husband and son she was exiled in Hungary. Two years later (ca. 1081/82) Boles?aw II died under mysterious circumstances, probably by poison. In 1086, together with her son Mieszko, Wyszes?awa returned to Poland. According to Gallus Anonymus, she participated in the funeral of her son, who was poisoned in 1089. This is the last mention of the wife of Boles?aw II the Bold; her fate remains unknown.
Modern historians, led by Oswald Balzer in his Genealogia Piastów (1895), refuted the name and origins of Boles?aw II's wife. They stated that she likely had a German or Russian origin. Also, there is the theory that the Queen Agnes (Agnes Regina) whose obituary is recorded in Zwiefalten was the wife of Boles?aw II; it is also believed that she belonged to the P?emyslid dynasty.
