Hamath-zobah was a place in ancient Israel. According to 2 Chronicles, it was conquered by Solomon and thus figured in his only military engagement alluded to in the biblical Books of Chronicles (2 Chr 8:3). Its exact location is uncertain.
Hamath and Zobah were likely adjoining kingdoms, whence the compound name "Hamath-Zobah", an idea supported by mention of wars between Hadadezer of Zobah and Toi of Hamath in 2 Samuel 8:9-10. According to Martin J. Selman, the existence of a joint name "Hamath-Zobah" indicated that by the time of Solomon the two kingdoms had joined into a single polity.
