Basel Poster Collection, Graphic design archive in Münchenstein, Switzerland.

The Basel Poster Collection (Plakatsammlung der Schule für Gestaltung Basel) is a public specialised poster archive holding around 100,000 posters as of 2021, covering culture, politics, business and consumer goods. Its focus is Swiss posters with local, content-related and design ties to northwestern Switzerland. It has been housed on the Dreispitz site in Münchenstein since 2018.

The collection traces back to 1896, when a successful exhibition of posters from the Strasbourg Kunstgewerbemuseum at the Basel Gewerbemuseum prompted the school to start its own collection; by 1905 it held nearly 600 posters. In 1916 director Hermann Kienzle tasked Max Bucherer with setting up a sample collection of applied graphics, and librarian Albert Baur took over its care, fully cataloguing around 1,600 posters in 1940. The school's departure from the shared Petersgraben-Spalenvorstadt building in 1961 weakened collecting activity; after the museum closed in 1996 the collection was attached to the Schule für Gestaltung and moved to the Dreispitz area in 2018.

The collection's focus today is Swiss posters with local, thematic and design ties to northwestern Switzerland, alongside older holdings in culture, politics, commerce and consumer goods. It grew through new acquisitions, reaching about 100,000 posters by 2021. The name refers to the poster collection of the Basel School of Design, to which it was attached after the Gewerbemuseum closed in 1996.

The collection has been housed on the Dreispitzareal in Münchenstein since its 2018 move, so it is no longer at the school's old Petersgraben site. It is a specialised archive rather than a gallery, so arrange access to specific posters in advance. The collection is catalogued, which makes targeted searches possible.

The collection's roots lie in a 1896 exhibition of posters lent by the Kunstgewerbemuseum Strasbourg, which prompted the Basel trade school to start its own holdings; by 1905 these had grown to nearly 600 posters. Librarian Albert Baur fully catalogued the roughly 1,600 posters in 1940.
