Ahmad al-Alawi (1869 – 14 July 1934), in full Abū al-ʿAbbās Aḥmad ibn Muṣṭafā ibn ʿAlīwa, known as al-ʿAlāwī al-Mustaghānimī (Arabic: أبو العباس أحمد بن مصطفى بن عليوة المعروف بالعلاوي المستغانمي), was an Algerian Sufi Sheikh who founded his own Sufi order, called the Alawiyya.

Al-Alawi was a Sufi shaykh in the classic Darqawi Shadhili tradition, though his order differed somewhat from the norm in its use of the systematic practice of khalwa and in laying especial emphasis on the invocation of the Supreme Name [of God].

He wrote poetry and books on established Sufi topics, and founded and directed two weekly newspapers, the short-lived Lisan al-Din (Language of Faith) in 1912, and the longer-lived Al-balagh al-jazairi (Algerian Messenger) in 1926.

For him, the answers to the challenges of modernity were the doctrines and practices of traditional and spiritual Islam and the rites of religion had no other purpose than to cause the "Remembrance of God".

"[3] The Alawiyya spread throughout Algeria, as well as in other parts of the Maghreb, as a result of Sheikh al-Alawi's travels, preaching, and writing and through the activities of his muqaddams (representatives).

Sheikh al-Alawi himself travelled to France in 1926, and led the first communal prayer to inaugurate the newly-built Grand Mosque of Paris in the presence of the French president.
