The Orbiting Human Circus (of the Air) is a fictional radio drama podcast written and created by Julian Koster, and published by Night Vale Presents.

The podcast stars Koster as Julian the janitor, a shy, sensitive employee of the Eiffel Tower who dreams of joining the fictional radio show also titled The Orbiting Human Circus of the Air, which is broadcast from a large ballroom at the top of the tower.

In addition to the conversations in his head, Julian interacts with the staff and talent of The Orbiting Human Circus of the Air, notably voiced by actors such as John Cameron Mitchell, Cecil Baldwin, Tim Robbins, Charlie Day, and Mary Elizabeth Ellis.

From June to July 2017, the podcast released "an Orbiting Human Circus Special," titled "The 2nd Imaginary Symphony," which served as the official wide-release of Koster's 2002 album.

[6] Koster cites British humor, specifically The Goon Show, as inspiration for some of the podcast's absurdism, in that jokes are delivered with little time for the audience to process the information.
