Nicephorus II of Constantinople

Nikephoros II or Nicephorus II (died 1261) was a Byzantine cleric and Patriarch of Constantinople in exile at the Empire of Nicaea.

Originally serving as Metropolitan of Ephesus, he was elected to the patriarchate after the resignation of Arsenios Autoreianos in 1260. He died after a few months, in early 1261, and was buried at Nymphaion. A period of vacancy followed his death, but after the reconquest of Constantinople in July, Arsenios was recalled from his retirement and restored to the patriarchal throne.
