Saul was a king of Edom mentioned in the Bible, in Genesis 36:31-43.
He succeeded Samlah of Masrekah in the apparently elective kingship of the early Edomites.
He is described as being from "Rehoboth on the River".
He was succeeded by Baal-hanan ben Achbor.
Although dates and other details of his reign are unknown - as he is not mentioned in any other surviving source - some have speculated that he might be Salatis, the first named Hyksos King.
