During the strike, it was unknown if production on the final episodes would resume or that a possible series finale would air due to the actors' contracts expiring if the strike were to last a long time. After the strike was over, the final five episodes aired starting April 10, 2008. Episode 12, titled "My Commitment" was partially completed before the strike, but was never completed or aired. Some material shot for "My Commitment" was later used in the season 8 episode, "My Nah Nah Nah".

The eighth season of the American comedy-drama television series Scrubs premiered on ABC on January 6, 2009 and concluded on May 6, 2009 and consists of 19 episodes. The eighth season was the first to be shown on ABC after NBC dropped the series, ending its seven-year run on the network. ABC's pick-up of the show was followed by it commissioning nineteen episodes, which included an hour-long finale. For all of the season's run, it was expected that the eighth season would be the last, especially after the show's creator Bill Lawrence announced it. After rumors surfaced of a ninth season, it was understood that the eighth would be the last to star Zach Braff and much of the main cast. However, the show was later re-commissioned for another season, in which Braff and other cast members appeared for multiple episodes. The eighth season was the first to air in high definition.
Needing to cut costs for the eighth season, Bill Lawrence stated that he divided the writing staff up into two groups, half for the first nine episodes and half for the second nine episodes. Additionally, each main cast member was absent for three episodes during the season. An accompanying web series that aired on ABC's website called Scrubs: Interns was also created to coincide with the season, starring the new interns with guest appearances by the main cast.

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.
