Kugelmugel, officially the Republic of Kugelmugel (German: Republik Kugelmugel), is a spherical art object located in Vienna, Austria.

It came about as the result of the artist Edwin Lipburger constructing the 8 square meter diameter spherical object without permissions from the authorities in Austria. After the dispute between the artist and authorities, the artist declared it a micronation, and it was eventually granted asylum by the then-mayor Helmut Zilk in Vienna where it is housed in the Prater park.

The 'Republic' is currently administered by Linda Treiber.
