(anc. geog.), a town lying upon the Euphrates, and belonging to the Assyrians. Necho king of Egypt took it from the king of Assyria, 2 Chr. xxxv. 20. Necho left a garrison in it, which was taken and cut to pieces, in the fourth year of Jehoiachin king of Judah, by Nebuchadnezzar king of Babylon, 2 Kings xxiii. 29. Isaiah (x. 9.) speaks of Carchemish, and seems to say, that Tiglath-pileser made a conquest of it, perhaps from the Egyptians. This is thought to be the same city with that called Circeium by the Greeks and Latins.
