Hadhramaut (Arabic: حَضْرَمَوْت, romanized: Ḥaḍramawt ; Hadrami Arabic: حَضْرَمُوت, romanized: Ḥaḍramūt ) is a geographic region in the southern part of the Arabian Peninsula which includes the Yemeni governorates of Hadhramaut, Shabwah and Mahrah, Dhofar in southwestern Oman, and Sharurah in the Najran Province of Saudi Arabia, and sometimes the Aden, Abyan and Lahij governorates of Yemen at a more stretched historical definition. The region's people are known as the Hadharem. They formerly spoke Hadramautic, an old South Arabian language, but they now predominantly speak the Hadhrami dialect of Arabic.
Though the origins of the name are unknown, the name Hadhramaut is traditionally explained as a compound word meaning "death has come" or "court of death," derived either from the Arabic ḥaḍara ("he came") plus mawt ("death"), a folk nickname for Amer bin Qahtan, the region's legendary first settler, or from the Biblical Hebrew ḥaṣar ("court" or "dwelling") plus māweṯ ("death") as seen in Hazarmaveth. The name is of ancient origin and is reflected in the name of the modern-day Yemeni governorate of Hadhramaut.
