Wenennefer (also Wennefer, Wennufer or Unnefer) was an ancient Egyptian High Priest of Osiris at Abydos, during the reign of pharaoh Ramesses II of the 19th Dynasty.

Wennufer's mother Maianuy was the daughter of the High Priest of Osiris To (sometimes called Tjay) and his wife Buia.

[3] Following a practice typical of the New Kingdom, Wenennefer inherited from his father the office of High Priest of Osiris, and after thirty-five years of priesthood he left it to his son Hori, who in turn was succeeded by Yuyu.

Mery is said to be the son of the Dignitary, God's Father and Sealbearer of Osiris Hat and his wife Iuy.

[11] This statue or architectural element comes from the funerary chapel of Wenennefer in Abydos and is now in the Athens Museum (Inv 106).

Behind his right arm is a text about "his brother" the Vizier Nebamun, who is said to be the son of the dignitary and Sem Priest Ramose and his wife Sheritre.
