Calendion (also, Calandion or Callandion) was a late-5th-century Patriarch of Antioch.
Calendion supported the results of the Council of Chalcedon in the factional disputes of the time. He refused to accept the Henotikon of 482, by which the Byzantine emperor, Zeno, attempted to reconcile the pro- and anti-Chalcedonian sides, since Calendion regarded it as a covert attempt to overturn Chalcedon. He supported the rebellion of Illus in 484, and as a result was deposed and banished by Zeno shortly thereafter, being replaced as Patriarch by Peter the Fuller.
