Ithier (or Itier, Iterius; died 981) was Archbishop of Arles from before March 963 until 981.
[1] He would then be a follower of King Conrad I of Burgundy, who became suzerain of Provence in 949.
Only a few elements of Ithier's life are known.
The prelates he appointed swore to him not only canonical obedience but also the oath of fidelity.
[5] The coinage of Arles, in decline since the end of the ninth century, was resumed under his archiepiscopate with coins bearing his initials.
