Nicetas I of Constantinople (or Niketas; Greek: Νικήτας; died 6 February 780) was the Ecumenical Patriarch of Constantinople from 766 to 780. He was of Slavic ancestry and he was a eunuch.

He was chosen by the Emperor Constantine V as a successor of the Patriarch Constantine II of Constantinople. However, Nicetas I was quite unpopular in Constantinople because he was a supporter of iconoclasm. After his death in 780, Nicetas I was declared a heretic. He was succeeded by Paul IV of Constantinople.
