The ninth and final season of the American comedy-drama television series Scrubs premiered on ABC on December 1, 2009 and concluded on March 17, 2010 and consists of 13 episodes. This season marked a major change in the series; it takes place at a different location and only three of the seven main characters from the first eight seasons remained as regular main characters. The rest of the cast is made up of new recruits, including Lucy, played by Kerry Bishé, who is also the show's new narrator. Former star Zach Braff returned for six episodes of the season.
The new season focuses on students at a med school at the fictional Winston University, rather than interns at a hospital. Doctors Perry Cox and Christopher Turk, played by John C. McGinley and Donald Faison respectively, returned as teachers. The show's filming location moved from the North Hollywood Medical Center to sets at Culver Studios. The series takes place at the new Sacred Heart Hospital, located on the Winston University campus.
The season takes place over a year after the events of the last episode of the eighth season, "My Finale", which was expected to be the last episode and ended many of the series' long-running storylines. However, Bill Lawrence was approached concerning more episodes, and as a result, the show entered its ninth season.
