Sergius II of Constantinople was an Eastern Orthodox prelate who served as the Ecumenical Patriarch from 1001 until his death in July 1019. Before his elevation to the patriarchal see, he acted as the abbot of the Monastery of Manuel, a monastery originally established by Photius I. Historical accounts by John Skylitzes suggest that he was a relative of the famous 9th-century patriarch Photius I. He held his position during the Byzantine Empire and was succeeded by Eustathius.

Sergius II rose to leadership within the church after serving as an abbot. His tenure as patriarch began in the summer of 1001. While historical records link him to the lineage of Photius I, later legends suggest he was involved in a conflict with Pope Sergius IV. He remained in his high office until he passed away in Constantinople in July 1019.

He is remembered as a saint within the Eastern Orthodox tradition. His leadership occurred during the pre-schism period of the church, and he is commemorated as a significant figure in the history of the patriarchal see of Constantinople.
