Leopold Stein (Yiddish: לעאפאלד שטיין; 3 November 1810 – 2 December 1882) was a German rabbi, theologian, and writer.

[3] After finishing his earlier education at Erlangen and Bayreuth, he began attending the University of Würzburg in 1830.

He received his rabbinic ordination from the Talmudic College in Fürth, and in 1833 he delivered his first sermon in Frankfurt, in which he advocated for the introduction of reforms.

[1] Stein translated Biblical and medieval poetry into German and added German texts to traditional melodies of the Hebrew liturgy, which were often included in public services.

[2] One of Stein's most popular writings was Die Schrift des Lebens ('The Scripture of Life'), an exposition of the dogmatics and ethics of Judaism.
