Nilus Kerameus (Νεῖλος Κεραμεύς; died 1 February 1388) was Patriarch of Constantinople between spring 1380 and 1388.[1] He was a Hesychast.
In 1380, he convened a synod to decide the metropolitanate of Moscow, choosing Bulgarian-born Hesychast Cyprian (1336–1406).
In 1382, Stephen of Perm wrote a letter to Nilus concerning the Strigolniki schism.[2]
