Jaromír (after 1035 – 26 June 1090[1]) was the Bishop of Prague from 1068, when he was appointed by his brother, Vratislaus II of Bohemia.
Jaromír even attacked the new bishop of Olomouc and carried off by force of arms the relics which had been removed from Prague to the new see.
Pope Alexander II sent the legate Rudolph to hold a diet in Prague in response to the conflicts surrounding the new see.
In 1085, John died, and a Reichstag convened in Mainz to suppress the Moravian see, re-uniting it to Prague by Jaromír's insistence.
Vratislaus fell out with Henry over the loss of Meissen and raised his chaplain Wecel to Olomouc as Bishop Andrew I. Jaromír went to Rome to protest to Pope Urban II.
