Ba'al-Perazim (Hebrew Owner of Breakings Through) was a place in ancient Israel. It was the scene of a victory gained by David over the Philistines (2 Samuel 5:20; 1 Chronicles 14:11). It is called Mount Perazim in Isaiah 28:21. It was near the Valley of Rephaim, west of Jerusalem. Some scholars suggest a site 4 km northwest of Jerusalem, named Sheikh Bodr, to be identical with Ba'al-Perazim.
