The Lenbachhaus (German: [ˈlɛnbaxˌhaʊs]) is a building housing the Städtische Galerie (English: Municipal Gallery) art museum in Munich's Kunstareal.

The group was founded in 1892, and included artists such as the impressionist painters Lovis Corinth (Self-portrait with skeleton 1896), Max Slevogt (Danae 1895) and Fritz von Uhde.

The Lenbachhaus is most famous for the worldwide largest collection of paintings by Der Blaue Reiter (The Blue Rider), a group of expressionist artists established in Munich in 1911 which included, among others, the painters Wassily Kandinsky (Impression III (Concert) 1911), Gabriele Münter (Still Life with St. George 1911), Franz Marc (Blue Horse I 1911), August Macke (Promenade 1913), Marianne von Werefkin (Self Portrait I c. 1910), Alexej von Jawlensky (Portrait of the Dancer Alexander Sacharoff 1909), Alfred Kubin (The Male Sphinx c. 1903), and Paul Klee (Föhn Wind in Franz Marc's Garden 1915).

The museum displays a broad view of international contemporary art with works by Franz Ackermann, Dennis Adams, Christian Boltanski, Monica Bonvicini, James Coleman, Thomas Demand, Olafur Eliasson, Valie Export, Dan Flavin, Günther Förg, Günter Fruhtrunk, Rupprecht Geiger, Isa Genzken, Liam Gillick, Katharina Grosse, Michael Heizer, Andy Hope 1930 (Andreas Hofer), Jenny Holzer, Stefan Huber, Asger Jorn, Ellsworth Kelly, Anselm Kiefer, Michaela Melian, Gerhard Merz, Maurizio Nannucci, Roman Opałka, Sigmar Polke, Arnulf Rainer, Gerhard Richter, Michael Sailstorfer, Richard Serra, Katharina Sieverding, Andy Warhol, Georgia O'Keeffe, Lawrence Weiner and Martin Wöhrl, as well as artists of the Viennese Actionism.

The Lenbachhaus has considerably strengthened its investment by acquiring numerous works of art, especially in the oeuvre of Joseph Beuys, such as Zeige deine Wunde (Show your wound) 1974/75.

Stephanie Weber curated a solo show of Mark Boulos and a film series of Charles Simonds and Christoph Schlingensief, while commissioning performances by Tom Thayer and C. Spencer Yeh and adding to the collection works by Vito Acconci, Valie Export and Martha Rosler, and has worked on a retrospective of Polish-born feminist artist Lea Lublin that opened in summer 2015.
