Flamingo, created by noted American artist Alexander Calder, is a 53-foot-tall (16 m) stabile located in the Federal Plaza in front of the Kluczynski Federal Building in Chicago, Illinois, United States. It was commissioned by the United States General Services Administration and was unveiled in 1974, although Calder's signature on the sculpture indicates it was constructed in 1973.

Alexander Calder was an American sculptor known both for his innovative mobiles that embrace chance in their aesthetic, his static "stabiles", and his monumental public sculptures. Calder preferred not to analyze his work, saying, "Theories may be all very well for the artist himself, but they shouldn't be broadcast to other people."
