Uroboros is an outdoor 1979 sculpture by Charles Kibby, located at Westmoreland Park in the Sellwood neighborhood of southeast Portland, Oregon.

[1] It is a modern depiction of the uroboros, an ancient Egyptian and Greek symbol depicting a serpent or dragon eating its own tail.

The organization lists "MAC 1979–80" as the funding source.

The Smithsonian categorizes Uroboros as abstract ("geometric") and notes that it was commissioned by the Comprehensive Employment and Training Act (CETA) before being donated to the park.
