Literaturfestival Zürich (alternative spelling: Zurich Literature Festival, formerly: Openair Literatur Festival Zürich) is an annual week-long international literary festival in Zurich. The main stage of the festival is located in the Old Botanical Garden in Zurich. The Festival is jointly presented by Literaturhaus Zürich and Kaufleuten, the two major institutions for literary events in Zurich. Founder and director of the festival is Swiss conceptual artist and curator Andreas Heusser who is curating the program together with Gesa Schneider and the management team of Kaufleuten.

The main program of the festival consists of premieres, performances and readings by international authors. The format "Words on Stage - Best of Spoken Word" has also established itself as a permanent feature of the program and closing event of the festival. Part of the festival's curatorial signature is its interdisciplinary approach: the readings are often thematically linked with projects from other genres, e.g. poetic installations, interactive radio plays, scenic readings, singer/songwriter concerts, silent film screenings, or interdisciplinary performances at the intersection of text, dance, and theater. ^[1] In interaction with nature and scenographic design, the aim is to create a "poetic overall experience" that involves all the senses. That is why the festival is often called "Switzerland's most beautiful literary festival".^[2]
