Arnold of Selenhofen (c. 1095/1100 – 24 June 1160) was the archbishop of Mainz from 1153 to his assassination in the Benedictine abbey St. Jakob, where he took shelter from the raging crowd.
He studied at the University of Paris and became the treasurer of the archdiocese of Mainz, then provost of the cathedral.
While he was away in Italy working for the recognition of the Antipope Victor IV in 1159, the leading citizens rebelled.
He was buried in the church of St. Maria ad gradus (St. Mary of the Steps).
