Rabbi Zvi Hirsch Grodzinsky (1857? in Minsk, Belarus – 1947 in Omaha, Nebraska, United States) was an American, Jewish, Orthodox Rabbi and author. His English name was Henry.
Zvi Hirsch studied under his famous second cousin Rabbi Hayyim Ozer Grodzinsky. In 1891, he accepted the rabbinate of the two Orthodox synagogues in Omaha. Zvi Hirsch was on par with the elite Jewish Law scholars of his day. He chose, however, to serve as rabbi in a religiously underdeveloped city so that he can pursue his scholarly endeavors. He was a composer of literature on Halakhic topics.Mikveh Yisrael (deals with the laws of Mikveh)
