The seventeenth season of the American medical drama television series Grey's Anatomy was ordered in May 2019, by the American Broadcasting Company (ABC), as part of a double renewal with the sixteenth season. Shortly after, Krista Vernoff signed an agreement to continue serving as the showrunner of the series. Filming on the series began in September 2020 while the season did not premiere until November 12, 2020, both dates being delayed as a result of the COVID-19 pandemic, for the 2020–2021 broadcast television season. The impact of the COVID-19 pandemic on television only allowed seventeen episodes to be produced, the fewest of any season since the fourth season. Numerous safety protocols were also implemented across various areas of production to prevent COVID-19 transmission.
All starring cast members from the previous season returned with the exception of Justin Chambers, who departed early in the sixteenth season. In addition, Richard Flood and Anthony Hill, who both appeared in the sixteenth season in recurring and guest capacities, respectively, received promotions to the main cast. This season also marked the return of former series regulars Patrick Dempsey, T. R. Knight, Chyler Leigh, and Eric Dane to the series. Meanwhile, main cast members Giacomo Gianniotti, Jesse Williams, and Greg Germann all departed the series during the season. Former series regular Sarah Drew also appeared in the season as part of Williams' departure.
Grey's Anatomy centers around the professional and personal lives of a group of medical professionals that work at the fictional Grey Sloan Memorial Hospital. Nearly every main storyline in the season centered around the COVID-19 pandemic, with a number of plot points also connecting to spin-off series Station 19 through fictional crossover events. The season primarily received mixed reviews from critics and remained ABC's most-watched scripted series, even though viewing figures dropped significantly from the previous season. The season eventually concluded on June 3, 2021. Despite initial uncertainty from the cast, crew, and the network, the series was eventually renewed for an eighteenth season.
