Samuel Baeck, also spelled Samuel Bäck (Hebrew: שמואל בק, born Boskowitz, Moravia, April 3, 1834 – died Lissa, May 11, 1912) was a German rabbi and father of Leo Baeck.
His father, Nathan Baeck, was rabbi in Kromau, Moravia; his grandfather, Abraham, rabbi in Holitsch, Hungary.
After being educated in the public schools of Kromau and at the Talmudic schools of Nikolsburg (Moravia) – now Mikulov – and Pressburg, Baeck studied at the University of Vienna, continuing his Talmudic studies under R. Horwitz.
He was a member of the municipal school committee and of the "Waisenrat", instructor in the Jewish religion at the gymnasium, and a delegate to the Deutsch-Israelitischen Gemeindebund.
He was the first to advocate with success the introduction of the teaching of the Jewish religion in the colleges of Prussia.
