Israelitische Religionsgesellschaft Zürich
Israelitische Religionsgesellschaft Zürich (literally: Israeli Religious Society Zurich, in Hebrew: עדת ישורון ציריך), commonly shortened to IRGZ, is one of two Hareidi communities in Zurich. 

The community has approximately 350 members, and it has been a member of the Schweizerische Israelitische Gemeindebund (SIG, literally Swiss Federation of Israelite Communities) since 1918.

In 1912, they started the .  The later is also a Hareidi community, but they pray according to Nusach Sefard.  Nevertheless, since the 1960s, there is a lot of cooperation between the communities, especially in the realm of Kashrut supervision.
