Mahmud Shukri al-Alusi (Arabic: محمود شكري الآلوسي, born 12 May 1856 – 8 May 1924) was an Iraqi Muslim scholar and historian who lived in Baghdad.

[1][2][3] A grandson of Mahmud al-Alusi, he is known for being a religious reformer and one of the early advocates of the Salafi movement.

[1][2] Muhammad Rashid Rida described him as “The supporter of the Sunnah, the suppressor of heresies, the sign of what has been transmitted and the discerner of those with reason, the living Islamic encyclopedia and the beacon of the Arabs.”[4] Mahmud Shukri al-Alusi was born on the 12th of May in the year 1856 in the Rusafa area of Baghdad.

[2][4] His rational and almost extremist tendencies regarding Sufism and creed earned him the scorn of the Ash'ari scholar Abu al-Huda al-Sayyadi who refuted him and requested Ahmed Abdel Wahab Pasha to send him into exile from Baghdad.

[2][5][4] Mahmud Shukri al-Alusi was an Athari in creed and a Hanafi in his jurisprudence, although he would sometimes identify with the Shafi'i school of thought.
