The Zumstein catalog is a postage stamp catalog from Switzerland. It has been issued regularly since 1909 and is considered to be an important reference work of Swiss philately. It is published in German and French languages. The Zumstein catalogs were originated by the philatelist , who founded the stamp shop Zumstein in 1905 and published the journal Philatelistische Börsennachrichten starting in 1907 (this journal is still published today, since 1915 under the name Berner Briefmarken-Zeitung).
