Otto of Freising (Latin: Otto Frisingensis; c. 1114 – 22 September 1158) was a German churchman of the Cistercian order and chronicled at least two texts which carries valuable information on the political history of his own time. He was the bishop of Freising from 1138. Otto participated in the Second Crusade; he lived through the journey and reached Jerusalem, and later returned to Bavaria in the late 1140s, living for another decade back in Europe.
