The Ba 'Alawi sadah or Sadah Ba 'Alawi (Arabic: السادة آل باعلوي‎, translit. al-sādatu al-bā'alawiy‎) are a group of Hadhrami Sayyid families and social group originating in Hadhramaut in the southwest corner of the Arabian Peninsula. They trace their lineage to al-Imam Ahmad al-Muhajir bin Isa ar-Rumi born in 873 (260H), who emigrated from Basra to Hadhramaut in 931 (320H) to avoid sectarian violence, including the invasion of the Qaramite forces into the Abbasid Caliphate. Ja'far was a direct descendant of the daughter of Muhammad, the prophet of Islam.

The word Sadah or Sadat (Arabic: سادة‎‎) is a plural form of word Arabic: سيد‎‎ (Sayyid), while the word Ba 'Alawi or Bani 'Alawi means descendants of Alwi (Bā is a Hadhramaut dialect form of Bani). In sum, Ba'alawi are Sayyids people who have a blood descendant of the Islamic prophet Muhammad through Alawi bin Ubaidullah bin Ahmad al-Muhajir. Meanwhile, Alawiyyin (Arabic: العلويّن‎‎; al-`alawiyyin) Sayyid term is used to describe descendants of Ali bin Abi Thalib from Husain ibn Ali (Sayyids) and Hasan ibn Ali (Sharifs). All people of Ba 'Alawi are Alawiyyin Sayyids through Husain ibn Ali, but not all people of Alawiyyin family are of Ba 'Alawi.
