George Habib Antonius, CBE (hon.) (Arabic: جورج حبيب أنطونيوس; October 19, 1891 – May 21, 1942) was a Lebanese-Egyptian author and diplomat, settled in Jerusalem, one of the first historians of Arab nationalism. Born in Deir al Qamar in a Lebanese Eastern Orthodox Christian family, he served as a civil servant in the British Mandate of Palestine. His 1938 book The Arab Awakening generated an ongoing debate over such issues as the origins of Arab nationalism, the significance of the Arab Revolt of 1916, and the machinations behind the post-World War I political settlement in the Middle East.
Antonius graduated from Cambridge University and joined the newly formed British Mandate Administration in Palestine as the deputy in the Education Department. His wife, Katy, was a daughter of Faris Nimr Pasha, a wealthy Syrian Christian and cultural activist. Antonius had a difficult relationship with the British. Despite his senior position he and his wife were refused membership of the Jerusalem sports club which had a "No Natives" policy.
An annual lecture is given in his memory at St Antony's College, Oxford.
