Ezion-Geber or Asiongaber (Classical Hebrew: עֶצְיֹן גֶּבֶר, pronounced "Etzyón-Gaver") was a city of Idumea, a biblical seaport on the northern extremity of the Gulf of Aqaba, in the area of modern Aqaba and Eilat.

Ezion-Geber is mentioned six times in the Tanakh Ruins at Tell el-Kheleifeh were identified with Ezion-Geber by the German explorer F. Frank and later excavavated by Nelson Glueck who thought he had confirmed the identification, but a later re-evaluation dates them to a period between the 8th and 6th centuries BCE with occupation continuing possibly into the 4th century BCE. According to the Book of Numbers Ezion-Geber was one of the first places where the Israelites camped after the Exodus from Egypt.

The ships of Solomon and Hiram started from this port on their voyage to Ophir. It was the main port for Israel's commerce with the countries bordering on the Red Sea and Indian Ocean. According to Book of II Chronicles, Jehoshaphat, the King of Judah, joined with Ahaziah, the King of Israel, to make ships in Asiongaber; but God disapproved the alliance, and the ships were broken in the port.
