Tabaqat al-Shāfi'iyya al-Kubra (Arabic: طبقات الشافعية الكبرى, lit.

'The Major Classes/Generations of the Shafi'is') is a voluminous encyclopedic biographical dictionary written by the Shafi'i-Ash'ari scholar Taj al-Din al-Subki (d. 771/1370), in which he presents biographies of scholars of the Shafi'i legal school in Sunni Islam, from the time of Muhammad ibn Idris al-Shafi'i (d. 204/820) all the way to his own contemporary time.

[1][2] The work also chronicles the history of the Ash'ari school of thought, since its beginning with Abu al-Hasan al-Ash'ari (d. 324/936) all the way to Taj al-Din al-Subki's own era; because most of the Ash'ari scholars are following the Shafi'i school of Islamic jurisprudence.

[3] The work is divided into seven classes (tabaqat), as follows:[4] In the last volume, al-Subki devotes about 150 pages to his own father, Shaykh al-Islam Taqi al-Din al-Subki (d.

756/1355).
