The Faisal–Weizmann agreement was signed by Emir Faisal, the third son of Hussein ibn Ali al-Hashimi, King of the short-lived Kingdom of Hejaz, and Chaim Weizmann, President of the Zionist Organization on 3 January 1919. Signed two weeks before the start of the Paris Peace Conference, it was presented by the Zionist delegation alongside a March 1919 letter written by T. E. Lawrence in Faisal's name to American Zionist leader Felix Frankfurter as two documents to argue that the Zionist plans for Palestine had prior approval of Arabs.

The Hashemite Kingdom of Hejaz was a state in the Hejaz region of Western Asia that included the western portion of the Arabian Peninsula that was ruled by the Hashemite dynasty. It was self-proclaimed as a kingdom in June 1916 during the First World War, to be independent from the Ottoman Empire, on the basis of an alliance with the British Empire to drive the Ottoman Army from the Arabian Peninsula during the Arab Revolt.
