Operation Yoav (also called Operation Ten Plagues or Operation Yo'av) was an Israeli military operation carried out from 15–22 October 1948 in the Negev Desert, during the 1948 Arab–Israeli War. Its goal was to drive a wedge between the Egyptian forces along the coast and the Beersheba–Hebron–Jerusalem road and ultimately to conquer the whole Negev. Operation Yoav was headed by the Southern Front commander Yigal Allon.
