Joseph ben Menahem Mendel Steinhardt (ca.
1720–1776) was a German rabbi who lived in his early year in Schwabach, Bavaria.
Steinhardt was one of the foremost Talmudists of his time, and questions were addressed to him from Hungary, Italy (Verona), the Netherlands (Amsterdam), and Switzerland.
He was very pious, and induced the lord of the manor of Nieder-Ehenheim to forbid men and women dancing together.
His attitude in his controversy with rabbi Yeshaye Pick regarding Eleazar Kalir is also noteworthy, since he maintained that the word "Be-Rabbi" was not a second name, but merely an honorary title of Kalir's, who he claimed was a contemporary of Saadia.
