The List of Swiss federal referendums details all federal referendums held in Switzerland since the establishment of the modern Swiss federal state in 1848. These referendums arise from:
Since federal popular initiatives always propose amendments to the Federal Constitution (rather than ordinary laws), they require both a majority of the popular vote and a majority of the cantons (known as the double majority) for approval. Six cantons, historically referred to as half-cantons, each carry half a cantonal vote. The same requirement applies to mandatory referendums and direct counter-proposals, as these are triggered by parliamentary amendments to the Constitution (). Optional referendums, which concern federal laws and certain international treaties, require only a majority of the popular vote for approval ().
The comprehensive list is organized by decade. Each section begins with links to annual overviews that briefly describe the proposals, followed by links to articles on specific proposals where available.

The Federal Constitution of 1848 "was not subjected to a nationwide federal referendum. However, most cantons conducted such a vote on their own initiative, as some had already done in 1833 for an unsuccessful revision of the Federal Treaty". At the time of the referendum on the Federal Constitution of 1848, the Federal Charter of 1815 was still in force, which did not provide a legal basis for conducting such a referendum; thus, this referendum does not meet the definition of a true mandatory referendum.
The first nationwide referendum was held by order of the Small Council of the Federal Council) of the Helvetic Republic on May 25, 1802, concerning the Second Helvetic Constitution.
From 1848 to the referendum on June 18, 2023, the following statistics apply:
