2121 Avenue of the Stars, formerly known as Fox Plaza, is a 34-story, 493-foot (150 m) skyscraper in Century City, Los Angeles, California.

[13] In 2024, Chicago-based law firm Katten Muchin Rosenman LLP moved into two floors on the property.

Fox Plaza features a unique HVAC system where a large vertical air shaft is located in the core of the building.

[14][15] In a 2018 tour for Variety, the chief engineer of the building noted how the Fox Plaza has a large number of redundancies in its design, and he speculates that it's because it was intended to be used as a filming location.

[17] The plaza and a neighboring building are the main setting for the 1994 comedy Airheads where fictional radio station KPPX is located.
