Mentuhotep II (, meaning "Mentu is satisfied"), also known under his prenomen Nephepetre (, meaning "The Lord of the rudder is Ra"), was an ancient Egyptian pharaoh circa 2061–2010 BCE, the sixth ruler of the Eleventh Dynasty. He is credited with reuniting Egypt, thus ending the turbulent First Intermediate Period and becoming the first pharaoh of the Middle Kingdom. He reigned for 51 years, according to the Turin King List. Mentuhotep II succeeded his father Intef III on the throne and was in turn succeeded by his son Mentuhotep III.
