Moshe Greenwald (1853–1910), also spelled Grunwald, a rabbi in Hungary at the end of the 19th century.

He was the rabbi of Chust, Hungary and progenitor of the Pupa Hasidic dynasty through his son Yaakov Yechezkiya.

He was also the author of Arugas Habosem, a book of responsa covering halakhic issues.

[2] His father died when he was twenty and he worked in timber trading, while continuing his studies.

[citation needed] At the age of twenty-six he began working as a rabbi in Humenné in Hungary (today in Slovakia).

Greenwald was originally from a non-hasidic family but as a young man he became a hasid and was a disciple of the second Belzer rebbe, Yehoshua Rokeach.
