Adolf Muschg (born 13 May 1934 in Zollikon, canton of Zurich) is a Swiss writer and professor of literature. Muschg was a member of the Gruppe Olten.

Adolf Muschg studied German studies, English studies and philosophy at the universities of Zürich and Cambridge and earned his doctoral degree with a work about Ernst Barlach.

Between 1959 and 1962 he worked as a teacher in Zürich. Different engagements as a teacher followed in Germany (Göttingen), Japan and the U.S.. From 1970 to 1999 Muschg was professor of German language and literature at the Eidgenössische Technische Hochschule, Zürich.

He wrote the foreword to Fritz Zorn’s controversial memoirs Mars. The book pointed out the supposedly “cancer-causing” lifestyle of Zurich’s wealthy gold coast and provoked a scandal in Switzerland; its author died of cancer before its release. Muschg was also provocative with works like Wenn Auschwitz in der Schweiz liegt ("If Auschwitz were in Switzerland"). His detractors^[who?] suggest that Muschg was writing without direct experience. A theme of his newer works is often love in old age.
