The Janice Dickinson Modeling Agency was a reality television series that debuted on Oxygen on June 6, 2006.

The first season follows her opening of the agency, including the difficulty in finding models of Janice's vision, getting them proficient in front of the camera, obtaining financial backing and establishing a reputation for her agency.
