Hamad Sa'b (surname also spelled Saab or Sa'ab, Arabic: حمد صعب) (21 April 1892 - 25 July 1941) was an Arab nationalist rebel commander from Lebanon.

[1] He was born to a Druze family in Kahlouniyeh in the Chouf region of the Mutasarrifate of Mount Lebanon during the Ottoman era.

[2] During the 1936-1939 Arab revolt in Palestine, Sa'b led a contingent of some 30 Lebanese volunteers, mostly Druze, to aid local rebels fighting against British rule and the growing Zionist movement.

[3] Sa'b and all of the volunteer contingents from the Arab world were under the overall command of Fawzi al-Qawuqji, a Syrian anti-colonialist rebel leader.

Much of Sa'b's activity was centered in northern Palestine, particularly around the village of Bal'a,[4] where his rebels fought a battle against British forces on 3 September 1936, in which two Druze volunteers were killed, including Mahmud Abu Yahya, a well-known rebel from the Great Syrian Revolt.
