Obelisk 11 March (full title: 11 March, This could be a Day of Historical Importance) is a 1979 outdoor obelisk memorial by the Yugoslav conceptual artist Braco Dimitrijević. It is located in the north-eastern end of the Schloss Charlottenburg park in Berlin, where it can be viewed during daylight hours, year-round. No admission fee required.

The obelisk is a commemoration of an arbitrary date, in fact the result of a chance meeting on a street in West Berlin, 1976. This "obelisk beyond history," as Dimitrijević has labeled it, is an early example of both a large-scale conceptual art work and an anti-monument. The project, initiated by the artist during a residency in Berlin in 1976, was completed in 1979 with the financial assistance of the Senate of Berlin, the Berlin Lottery Foundation, DAAD and the former Verwaltung der Staatlichen Schlösser und Gärten in West Berlin.
