The Surafend affair () was the premeditated massacre of many male inhabitants from the Arab village of Surafend (now the area of Tzrifin in Israel) and a Bedouin camp in Palestine by soldiers of the ANZAC Mounted Division on 10 December 1918. The massacre, believed to have been in response to the murder of a New Zealand soldier by a villager, was mostly overshadowed by the military achievements of the Division, although it caused a significant rift between the Division and its Commander-in-Chief, General Sir Edmund Allenby.
