Joel Deutsch (Hebrew: יוֹאֵל דוֹיטְשׁ; (1813-03-20)20 March 1813, Nikolsburg – (1899-05-01)1 May 1899, Vienna) was a Moravian Jewish writer, pedagogue, and distinguished deaf educator.

He was a close student of rabbinical literature and an energetic collector of Hebrew books.

In 1844, he became a teacher at the Allgemeine österreichische israelitische Taubstummen-Institut in Nikolsburg, a school for deaf Jewish children established that year by philanthropist Hirsch Kolisch at the suggestion of Catholic priest Dr. Franz Herrmann Czech.

[2] In a letter to Edward Walter, director of the Institute for the Deaf in Berlin, Deutsch asserted that the students who had undergone their training programme were of decided intelligence, contrary to contemporary thought about deaf-mutes.

In support of this contention, he sent an essay by one of his students, Bernhard Brill, and said that he doubted whether any non-disabled person "could match his lucid and incisive style.
