Saqr bin Zayed Al Nahyan was the Ruler of Abu Dhabi from 1926 to 1928. He was the half brother of Sultan bin Zayed bin Khalifa Al Nahyan (Ruler of Abu Dhabi from 1922 to 1926), whom he shot and killed to become Ruler himself. He was the uncle of Zayed bin Sultan Al Nahyan and Shakhbut bin Sultan Al Nahyan, his successor.
At the instigation of Khalifah bin Zayed, the Emir Saqir was assassinated on New Year's Day 1928 by members of the Al-Bu Shaar sect of the Al Manasir, who installed Shakhbut bin Sultan Al Nahyan, the son of Saqr's predecessor and brother, Sultan bin Zayed, as the new Emir. Shakhbut became the new ruler of Abu Dhabi.
