Samuel Cahen (4 August 1796, Metz, France – 8 January 1862, Paris) was a French Hebraist and journalist.
He pursued a course of rabbinical studies while simultaneously devoting much attention to modern languages and literatures.
In 1822 he went to Paris, where he assumed the directorship of the Jewish Consistorial School, a position which he held for a number of years.
In 1840, Cahen founded the Archives Israélites, a French Jewish review.
Cahen's main work was the translation of the Jewish Bible into French, with the Hebrew on opposite pages, and critical notes and dissertations by himself and others.
