The Gebel el-Arak Knife, also Jebel el-Arak Knife, is an ivory and flint knife dating from the Naqada II period of Egyptian prehistory (3500—3200 BC), showing Mesopotamian influence. The knife was purchased in 1914 in Cairo by Georges Aaron Bénédite for the Louvre, where it is now on display in the Sully wing, room 633. At the time of its purchase, the knife handle was alleged by the seller to have been found at the site of Gebel el-Arak, but it is today believed to come from Abydos.
