Sheikh Farhan al-Saadi (circa 1862 – 27 November 1937) was a Palestinian rebel commander and revolutionary who rose to prominence during the 1936–1939 Arab revolt in Palestine.

When he was released from prison, he moved to Haifa where he met Sheikh Izz al-Din al-Qassam and joined his organisation.

[2] On 15 April 1936, a group called Ikhwan al-Qassam under al-Sa'di's leadership ambushed a bus on the Nablus-Tulkarm road.

For the many operations against the British, he was sentenced to death for carrying a single bullet.

[4] Sa'adi was executed on 27 November 1937, at the age of 75 during the Ramadan fast.
