The Third Battle of Ramla (or Ramleh) took place on 27 August 1105 between the Crusader Kingdom of Jerusalem and the Fatimids of Egypt. The town of Ramla lay on the road from Jerusalem to Ascalon, the latter of which was the largest Fatimid fortress in Palestine. From Ascalon the Fatimid vizier, Al-Afdal Shahanshah, launched almost annual attacks into the newly founded Crusader kingdom from 1099 to 1107. Of the three battles the Crusaders fought at Ramla early in the twelfth century, the third was the most bloody.

The Franks appear to have owed their victory to the activity of Baldwin. He vanquished the Turks when they were becoming a serious threat to his rear, and returned to the main battle to lead the decisive charge which defeated the Egyptians." Despite the victory the Egyptians continued to make annual raids into the Kingdom of Jeruselum with some reaching the walls of Jerusalem itself before being pushed back.
