Ma'rib (Arabic: ?????) or Marib is the capital city of the Ma'rib Governorate; Yemen and was the capital of the Sabaean kingdom; which some scholars believe to be the ancient Sheba of biblical fame. It is located at approximately 120 kilometers east of Yemen's modern capital; Sana'a.

The Sabaean kingdom was located in what is now Marib in southwestern Yemen. The Sabaean kings made their capital at Ma'rib; and built great irrigation works such as the Ma'rib dams; whose ruins are still visible. The Marib Dam supported a flourishing culture for more than a thousand years before collapsing in 575 CE. They also built castles and temples in the area; and were known for trading valuable frankincense and myrrh. They were a seafaring people and known to have influence and a population in the Northeast African kingdom of D?mt; across the Red Sea in Eritrea and perhaps Ethiopia; the only other source of both frankincense and myrrh.
