The Philadelphia Yellow Jackets were a professional indoor football team and a member of the American Indoor Football league that played half a season in 2016 before folding due to financial issues.

On June 11, 2015, the AIF announced the Yellow Jackets would be joining for the 2016 season.

The "P-Y-J" are owned by Joe Krause, owner of the Indoor Gridiron League.

[1] The Yellow Jackets played their home games at the Class of 1923 Arena on the campus of the University of Pennsylvania the majority of their first season until May 11, 2016, when the university voided their contract for lack of payment leading to cancelling their last three games.

Owner Joe Krause released a statement on the team's Facebook account accusing the university of breach of contract while he was dealing with his wife's recovery from a stroke.
