Production
On January 31, 2019, The CW renewed the series for a fifteenth season. On March 22, series stars Jared Padalecki, Jensen Ackles, and Misha Collins announced that the 20-episode fifteenth season of Supernatural would also be its last, making it the longest-running series on The CW. Ackles, who last directed the episode "The Bad Seed" from the eleventh season, directed the first episode filmed for the season, which aired chronologically as the fourth episode. Other cast members directing episodes for the season include returning director Richard Speight Jr. and young John Winchester actor Matt Cohen. Jake Abel reprises his role as the Winchesters' long-lost half-brother Adam Milligan, who last appeared in the fifth-season finale.

The series finale was originally set to air on May 18, 2020; however, on March 12, 2020, Warner Bros. Television shut down production on the series due to the COVID-19 pandemic. On March 23, showrunner Andrew Dabb revealed that the season would go on hiatus after the March 23 episode. Dabb clarified that the series had completed production on 18 of the 20 episodes for the season, but the post-production process could not be completed on the episodes because of the shutdown due to the virus outbreak. Dabb also assured that the series' cast and crew, The CW, and Warner Bros. were fully committed to filming and airing the unproduced episodes with its proper finale. On August 17, 2020, The CW announced that the season would resume airing on October 8, 2020, and the series finale aired on November 19, which was preceded by a special titled The Long Road Home.
