Thierry Bianquis (1935 – 2 September 2014) was a French Orientalist and Arabist.
His main interest was the medieval Islamic Middle East, most notably the Fatimid era of Egypt and Syria, which was the subject of his dissertation.
Born in Broummana, Lebanon, in 1935, he spent his childhood in the country before coming to France for his higher education.
Alongside his own voluminous publications, he served as an editor of the second edition of the Encyclopaedia of Islam, and was one of the main authors of The Cambridge history of Egypt: Islamic Egypt (641-1517).
