Khalifa bin Zayed bin Khalifa Al Nahyan (Arabic: ٱلشَّيْخ خَلِیْفَة بِن زَایِد بِن خَلِیْفَة آل نَهْيَان, romanized: Ash-Shaykh Khalīfah bin Zāyid bin Khalīfah Āl Nahyān) was the eldest son of Abu Dhabi ruler Zayed bin Khalifa Al Nahyan.^[1] He was brother of four Abu Dhabi rulers, Tahnoun, Hamdan, Saqr and Sultan. Khalifa refused to ascend the throne when his father died in 1909,^[1] because his mother begged him to refuse, as she was sure he would be killed. He reportedly built Al-Muwaiji Fort in what is now the city of Al Ain during the early 20th century, during the reign of his father.^[2]

Khalifa's grandsons, Hamdan, Mubarak, Tahnoun and Saif, were the major supporters of Zayed bin Sultan when he became the ruler of Abu Dhabi in 1966.^[3] They assumed various major public roles.^[3] He is the great-grandfather of Nahyan bin Mubarak Al Nahyan.
