Hadoram (Hebrew: הֲדוֹרָם Hăḏōrām) is the son of Joktan mentioned in the Book of Genesis of the Hebrew Bible. Noah had three sons: Shem, Ham, and Japheth. One of Shem's sons was Arpachshad. One of Arpachshad's grandsons was Eber. Eber had two sons: Peleg and Joktan.
Joktan had many sons including Hadoram as the Book of Genesis (10:26-30) states:
According to Rabbi Aryeh Kaplan's footnotes: "Hadarom: Some interpret this as denoting 'the south.' This was a fortress to the south of (Yemen's) Sana'a (Kesseth HaSofer). See 1 Chronicles 18:10; Zechariah 12:11."[2]
Hadoram was also the name of the son of the king of Hamath, Tou, in 1 Chronicles 18.
