Abu'l-Fath, or Ibn Abi al-Hasan al-Samiri al-Danafi, was a fourteenth-century Samaritan chronicler, writing in Arabic. His major work is Kitab al-Ta'rikh.
The work was commissioned in 1352 by Pinḥas, Samaritan high priest, and begun in 1356. It is a compilation of Samaritan history from cited earlier sources, running from Adam to Mohammed.
It was edited by Eduard Vilmar as Abulfathi annales Samaritani (Gotha, 1865).
