Bolko III of Strzelce (also known as of Opole; Polish: Bolko III Strzelecki (or Opolski); c. 1337 - 21 October 1382) was a Duke of Opole during 1356-1370 (with his brothers as co-rulers) and Duke of Strzelce from 1375 until his death.
After his father's death in 1356, Bolko III and his brothers W?adys?aw Opolczyk and Henry inherited Opole as co-rulers; however, the full government was held by the oldest brother, W?adys?aw Opolczyk.
Bolko III spent much of his time at the courts of King Charles in Prague and King Louis I in Buda. In 1355, Bolko III, with several other Silesian Dukes, went to Italy with King Charles of Bohemia, who came to Rome for his coronation as Holy Roman Emperor; ten years later, in 1365, he made a journey from Luxembourg to Avignon, and in 1377, together with King Louis I of Hungary and W?adys?aw Opolczyk, he made a military expedition to Be?z.
Bolko III died on 21 September 1382 and was buried in the Franciscan chapel of St. Anna in Opole. Upon his death, his title passed to his four sons as co-rulers. Because his sons were minors, their guardianship was held by his uncle W?adys?aw Opolczyk.
