Abraham (Hebrew:  אַבְרָהָם (help·info)) is the founding father of the Israelites, with a prominent role in Judaism, Christianity and Islam.

The story of Abraham is told in chapters 11:26-25:18 of the book of Genesis. It is essentially the history of the establishment of the covenant between Abraham and God: God calls Abraham to leave his land, family and household in Mesopotamia in return for a new land, family and inheritance in Canaan, the promised land; threats to the covenant arise (difficulties in producing an heir, the threat of bondage in Egypt, of lack of fear of God); but all are overcome and the covenant is established. Abraham's story ends with the death and burial of his wife Sarah in the grave which he has purchased in Hebron (a town in southern Judah), followed by the marriage of his heir Isaac to a wife from his own people: these two episodes signify Abraham's desire of the land for his descendants and the exclusion of land's previous inhabitants, the Canaanites, from its ownership.

The Bible's internal chronology places Abraham and the patriarchs in the second millennium BCE, but the stories in Genesis cannot be related to the known history of that time, and most biblical histories no longer begin with the patriarchal period.
