Ilona Ruegg (b. 1949, Rapperswil, Switzerland) is a visual artist working across sculpture, installation, and photography. Her practice engages with architecture, display, and systems of representation, often employing serial structures and modular forms to explore spatial perception and the conditions of exhibition-making. Through precise, reduced interventions, her work examines the relationship between object, image, and environment.

Over the course of her career, she has received several prestigious honors, including the Prix Meret Oppenheim (2001), the Recognition Prize of the Kulturstiftung UBS (2004 and 2013), and the Prix Visarte for Art and Architecture (2023). Earlier on, she was awarded the Louise Aeschlimann Scholarship and a residency at the Istituto Svizzero in Rome, both in 1984.

Ruegg’s work has been presented in numerous important institutions, including the Swiss Institute in New York, Kunsthalle Bern, Musée cantonal des Beaux-Arts Lausanne, Kunsthalle Arbon, Kunsthaus Zürich, Museum Haus Konstruktiv in Zurich, Kunstmuseum St. Gallen, Shedhalle Rote Fabrik in Zurich, and Aargauer Kunsthaus, among others. Her works are held in major public and private collections.
