Francisco Codera y Zaidín (Huesca, Spain, 23 June 1836 [1]– 6 November 1917)[2] was a Spanish historian, philologist and Arabist scholar.

Among his students, known in the academic field as the Beni Codera, [3][4] were Arabists Rafael Altamira and José Deleito.

As the principal student of Pascual Gayangos, he was an outstanding Arabist and succeeded him to the chair of Arabic at the Central University.

[7] Rigorously positivist, his works generally focus on historiographic sources of Arab origin (Estudios de historia arábigo-española, Decadencia y Desaparición de los Almorávides en España, 1899, reissued with an important introductory study by María Jesús Viguera Molins in 2004).

He retired to his native town of Fonz, in the province of Huesca, to devote himself to his scholarly studies and the writing of treaties on agriculture.
