Hezekiah ben Manoah (13th century) or Hezekiah bar Manoah, known as the Hizkuni (Hebrew: חזקוני) was a French rabbi and student.
In memory of his father, who lost his right hand through his steadfastness in the faith, Hezekiah wrote a commentary on the Pentateuch, under the title Ḥazzeḳuni (ca. 1240). It was printed at Venice in 1524. Other editions appeared at Cremona (1559), Amsterdam (1724, in the Rabbinical Bible of M. Frankfurter), Lemberg (1859), etc. It is based principally upon Rashi, but it uses also about twenty other commentaries, though the author quotes as his sources only Rashi, Dunash ben Labrat, the "Yosippon", and a "Physica" which is mentioned in the Tosafot (to Lev. xii. 2). He is generally cited by the title of his commentary.
