Jarosław Opolski (b. between 1143-1160 - d. 1201) was a duke of Opole from 1173 and bishop of Wrocław from 1198.
He was the oldest son of Bolesław I the Tall, but family politics forced him into a religious career (in 1160s or 1170s). Jarosław was not content with being removed from power (as the first born son he should have inherited Bolesław's part of the Duchy of Silesia, and during the civil war in 1172-1173 he managed to take control of the lands around Opole.
