瑞士国家银行（德语：Schweizerische Nationalbank；法语：Banque Nationale Suisse；意大利语：Banca Nazionale Svizzera；罗曼什语：Banca Naziunala Svizra）是瑞士的中央银行，负责瑞士的货币政策以及瑞士法郎的发行。

瑞士国家银行是一个特别管理的股份制公司。约55%的股份是由公共机构掌握，例如州或州银行。剩下的股份则在交易所上市交易，主要为个体投资者拥有。瑞士联邦并没有其股份。

The Swiss National Bank (SNB) is the central bank of Switzerland, and so is therefore responsible for the monetary policy of the nation of Switzerland and also for the issuing of Swiss franc banknotes.

The bank is otherwise known as: German:Schweizerische Nationalbank; French:Banque nationale suisse; Italian:Banca nazionale svizzera; Romansh:Banca naziunala svizra, which are the four official languages of the country.
