Patriarch Philotheus I of Constantinople

Philotheus Kokkinos (Thessaloniki c. 1300 – Constantinople 1379) was the Ecumenical Patriarch of Constantinople for three periods from November 1353 to 1354, 1354, and 1364 to 1376. He was appointed patriarch in 1353 by the emperor John VI Cantacuzenus, deposed by John V Palaeologus in 1354 and then restored by Patriarch Callistus I of Constantinople.

During the third tenure starting from 1364, Philotheus opposed the emperor John V in his intent to negotiate with Pope Urban V and Pope Gregory XI.
