Abraham is traditionally believed to have been born in "Ur of the Chaldees" (Ur Kasdim), which most scholars identify with the ancient Sumerian city of Ur, located in southern Mesopotamia near present-day Nasiriyah in Iraq

. This city was a significant urban center in the ancient world and is mentioned in the Bible as Abraham's birthplace. There is, however, some debate and alternative traditions:

• Some Jewish exegetes, like Nahmanides, suggest Abraham was actually born in Haran (in Upper Mesopotamia, modern southeastern Turkey or northern Syria) and later moved to Ur

• Another older tradition places Abraham's birthplace in the city of Urfa (Edessa) in southeastern Turkey

• The Torah also refers to Abraham's birthplace as Ever-haNahar ("Beyond the River"), which can be interpreted as a region east of the Euphrates River, consistent with either Ur or Haran

Despite these variations, the predominant scholarly and biblical consensus is that Abraham was born in Ur of the Chaldees, the ancient city of Ur in southern Mesopotamia. In summary, Abraham was most likely born in the ancient city of Ur in southern Mesopotamia, though some traditions hold Haran or Urfa as his birthplace
